Overview

Smaug the Impenetrable is a damage-to-mana converter wearing a dragon costume. Flying, indestructible, haste, 8/7 — and every point of noncombat damage he's dealt becomes that many Treasures, in one trigger, from anyone's source. The whole deck is built to exploit the fact that indestructible makes the conversion free: your removal, your board wipes, your enchantment drips, and even your opponents' pings all pay you.

The engine has two speeds:

• The trickle — Black Market Connections, Smaug the Magnificent's upkeep Treasure, Ragavan and Face-Breaker connecting, Revel in Riches taxing every dead opponent creature. This is turns 1–4: quiet, steady accumulation while you ramp toward the dragon.
• The geyser — Smaug lands, and suddenly every damage spell is a mana spell. Cut Propulsion at him is 16 Treasures for (8 power, doubled for flying). Blasphemous Act is 13. Star of Extinction is 20 and a board wipe he ignores. Dawnsire at 10+ charge counters shoots him for 100.

What you do with the hoard is genuinely flexible, and no line is "the" line — the pile itself is the plan:

• Spend it: Torment of Hailfire or Exsanguinate with X in the double digits ends the table. Goldspan Dragon doubles every Treasure's output on the way.
• Count it: Revel in Riches (10 Treasures) and Knuckles the Echidna (30 artifacts — Academy Manufactor's Clues and Food count) just win at your upkeep.
• Bleed with it: Mirkwood Bats, Nadier's Nightblade, Reckless Fireweaver, and Ingenious Artillerist turn every Treasure created and every Treasure spent into damage. A big geyser with Bats out often kills before you spend a single token.

Red is the deck's hungry color (about 72% of pip demand on 56% of sources) — in a close keep, weight hands toward red sources. Treasures fix everything once the engine turns over.

Mulligan Guide

Mulligan for curve. The keep question: "does this hand do something every turn and land Smaug on time?"

Keep a hand with:

1. Three lands (or two plus a mana rock / Black Market Connections);
2. A play on turn 2 and turn 3 — a Signet/Talisman, Black Market Connections, an early Treasure-maker (Ragavan, Smaug the Magnificent, Face-Breaker);
3. A route to casting Smaug by turn 4–5.

Ship:

• All-payoff hands — Revel, Torment, Fiery Emancipation with no engine under them do nothing for five turns;
• All-interaction hands that never develop;
• Hands that can't hit seven mana on schedule and aren't building the trickle in the meantime.

The payoffs are dense enough that you'll draw into them; the curve is what you can't fix later.

Game Plan

• Turns 1–3: build the trickle. Rocks and Treasure-makers out, Black Market Connections online (Treasure mode early, cards later). Hold a cheap answer up when convenient — Abrade, Terminate, and the redirect suite are cheap enough to leave open — but don't let interaction cost you a development turn.
• Turns 4–5: land the dragon. Ideally with one mana up or a Hexing Squelcher already down (your spells can't be countered under it). Smaug has haste and evasion, and an 8/7 flier does honest work — but combat is the side hustle. He's on the battlefield to be a target.
• Sequencing rule: Smaug first, burn second. Every damage spell cast before he lands is just a spell; every one cast after is ramp. Blasphemous Act with three creatures on the board is very castable — save it for when the wipe pays.
• The geyser turn: convert a wipe or a self-burn spell into a pile, then spend it immediately — Torment/Exsanguinate for lethal, or a fistful of card flow (Big Score, Unexpected Windfall, Face-Breaker exiles, Fomori Vault digging as deep as your artifact count, Idol of Oblivion drawing every token turn). Smaug, Wicked Worm arrives with Treasures matching your opponents' artifact count and then pays you a card (for 1 life) on every spell you cast with Treasure mana — with a hoard up, he's a draw engine strapped to a 6/6 flier. Rain of Riches gives your first Treasure-funded spell each turn cascade — with a pile up, that's a free spell every turn including opponents' turns.
• Protect the win, not the dragon. Smaug barely needs protecting — indestructible dodges wipes and burn; the real threats are exile and edicts. Deflecting Swat and Bolt Bend (usually 0 and 1 mana here) retarget removal, Return the Favor copies or redirects, and The One Ring buys a full turn of protection from everything to untap into the kill. Swiftfoot Boots stops targeted exile outright.
• Opponents get charged too. Bowmasters taxes their draws (the ping can target your own Smaug — a Treasure per extra draw), Revel taxes their dead creatures, Mayhem Devil taxes their fetches and sacrifices, and the redirect suite turns their burn spells into your Treasures.

How Smaug's trigger actually works

• Any source, any controller. Opponents' pings, your own spells, ability damage — if it's noncombat damage dealt to Smaug, it mints. Opponents learn fast to stop pointing burn at him; Bolt Bend and Untimely Malfunction make sure they pay anyway.
• One damage event = one trigger for that many Treasures. Blasphemous Act's 13 arrives as one trigger making 13 Treasures — which matters for the doublers:
  • Xorn adds one Treasure per creation event, not per Treasure (13 → 14, not 26).
  • Academy Manufactor turns each Treasure-creation into Clues + Food + Treasures. When both apply, order Xorn first: 13 → 14 Treasures → 14 of each. The Clues and Food feed Knuckles' artifact count and trigger Mirkwood Bats like any token.
• Fiery Emancipation triples damage from sources you control — your Bolt at Smaug makes 9, Blasphemous Act makes 39, each Pestilence activation makes 3. Opponents' damage isn't tripled — and note it triples your sources' damage to you as well (see Pitfalls).
• Toughness is irrelevant. Damage far beyond 7 still counts in full, and indestructible means lethal damage never matters. Star of Extinction's 20 to an 8/7 is 20 Treasures.
• The One Ring's protection is loop armor. Protection from everything prevents all damage that would be dealt to you — including from your own Pestilence and Pyrohemia. For one turn cycle the "each player" clause skips you entirely.

Key Loops & Interactions

• Pestilence / Pyrohemia never leave. Their end-step self-sacrifice needs a creatureless board — indestructible Smaug guarantees a creature survives every wipe, so they stick around forever. Each activation deals 1 to every creature and every player, and Smaug pays you back the mana: the loop is mana-neutral board erosion that melts opponents' creatures (feeding Revel), drains all life totals, and with Xorn out actually profits a Treasure per activation.
• Smaug the Magnificent doubles the hoard every attack. His attack trigger deals damage equal to your Treasure count to any target — point it at Smaug the Impenetrable. Ability damage is noncombat even during combat, so X Treasures become 2X on every swing. His upkeep also drips one for free.
• Self-burn as instant-speed ramp. Cut Propulsion at Smaug: 16 Treasures for (flying doubles it). Self-Destruct: 8 Treasures plus 8 damage at any other target — removal that pays you. Both are instants, so they're also "build to 10 Revel Treasures on the end step before your upkeep" spells.
• Pain for All on Smaug turns the mirror around. Every hit he takes is dealt to each opponent in full — Blasphemous Act becomes 13 Treasures + 13 to everyone, and a Dawnsire shot becomes table-lethal (see Combos). The two equipment triggers are weaker cousins with a key difference: Blazing Sunsteel deals the damage dealt to any one target; Fiendlash deals only the equipped creature's power to a player.
• Pariah's Shield on Smaug is a personal Fort Knox — for noncombat damage. Opponents' burn, Pestilence hits, and drain-adjacent damage aimed at your face get dealt to Smaug instead and mint Treasures. Redirected combat damage is still combat damage — no Treasures, but an indestructible 8/7 soaks it for free, so attacking you becomes pointless either way.
• The drain shell makes the hoard itself lethal. Mirkwood Bats drains 1 per token created and again per token sacrificed — a Treasure's full life cycle is 2 damage to each opponent. Nadier's Nightblade adds a drain-and-gain on every token leaving; Reckless Fireweaver and Ingenious Artillerist hit on every artifact entering (Artillerist scales with the whole batch); Agent of the Iron Throne gives Smaug-on-the-battlefield a drain for every artifact or creature of yours hitting the graveyard. Stack two of these and a 13-Treasure geyser deals 26+ to each opponent before you've spent a token.
• The redirect suite is also ramp. Bolt Bend, Untimely Malfunction, Return the Favor, and Deflecting Swat move opponents' burn and targeted removal onto Smaug — their Lightning Bolt at your Bats becomes your 3 Treasures.
• The combat engine runs in parallel. Ragavan, Face-Breaker, Knuckles, and Ancient Copper Dragon (d20 Treasures on connect) mint off combat damage — Smaug's trigger never sees combat, but these don't need it to. Knuckles is also quietly the deck's second alt-win: with Manufactor turning every windfall into triple tokens, thirty artifacts arrives faster than tables expect.
• Spinerock Knoll is always on. "An opponent was dealt 7 or more damage this turn" is trivial here — one geyser or Pestilence session unlocks the hideaway.
• Utility one-liners: Urza's Saga fetches Sol Ring or Mox Opal (and its Constructs scale with the hoard); Command Beacon is the tax valve when Smaug's been exiled a couple of times; Fomori Vault digs X = your artifact count, which late-game is "look at most of your library."

Combos

The house line first, then the full Commander Spellbook list. All of the Smaug loops are commander-dependent and none comes online before he does — this is a late-game, take-what-arrives combo suite.

Dawnsire shoots Smaug — the signature play

Dawnsire, Sunstar Dreadnought + Smaug the Impenetrable → ~100 Treasures → lethal X-spell.

1. Station Dawnsire to 10+ (sorcery speed): tap Smaug — his 8 power is 8 charge counters — plus any other creature with power 2+ (Knuckles, a Construct, Mayhem Devil). Two taps and you're armed. Dawnsire itself stays a noncreature artifact below 20, so most removal misses it.
2. Attack with anything. The 10+ ability reads "whenever you attack" — Dawnsire doesn't attack, and the trigger fires when you declare any attacker, even a dashed Ragavan.
3. Target Smaug with the trigger: 100 noncombat damage → 100 Treasures (101 with Xorn; 100 Clues and Food each with Manufactor; with Mirkwood Bats out, creation alone drains 100+ per opponent — already lethal).
4. Second main: spend it. Torment of Hailfire or Exsanguinate for X ≈ 98 ends the table twice over. With Goldspan Dragon out the pile taps for ~200.

If Revel in Riches is down instead, you can also just... pass, and win at your upkeep. Both doors are fine. The dragon is happy either way.

The Commander Spellbook five

• Dawnsire + Pain for All — table damage. The 100-damage shot hits your enchanted creature; Pain for All deals the full 100 to each opponent. On Smaug, this is simultaneously 100 Treasures. Pain for All fires even if the damage would be lethal to the wearer (official ruling), so any creature you control can take the bullet.
• Dawnsire + Fiendlash — single-target burn. Same shot at the equipped creature, but note the brief overstates this one: Fiendlash deals the equipped creature's power to a player — 10 on Smaug (8+2) — not the 100 that hit it. On Smaug it's really "100 Treasures, plus 10 at someone's face."
• Smaug + Mayhem Devil — infinite colored mana. Sacrifice a Treasure for mana → Devil pings Smaug (you choose the target on any player's sacrifice) → Smaug mints a replacement. Net: a Treasure per Treasure, one floating mana per loop, and infinite sacrifice/ETB/LTB triggers — with Bats or Nightblade out that's 2+ drain to each opponent per loop, and with Xorn the hoard itself grows infinitely. Empty the mana into Torment or Exsanguinate.
• Smaug + Pyrohemia — near-infinite everything, to start. Activate Pyrohemia: 1 damage to each creature and each player → Smaug mints 1 → sacrifice it for → repeat. Mana-neutral for as long as you like: every non-indestructible creature dies (Revel collects), every opponent's life total walks to zero. You take each hit too — see Pitfalls.
• Smaug + Pestilence — the same loop in black, to start. Redundant copy of the engine; with both down you can alternate off any mix of B/R Treasures.

Common Pitfalls

• Pariah's Shield doesn't mint off combat. Redirected combat damage is still combat damage — Smaug soaks it, but zero Treasures. Don't count blocked-face math as ramp.
• Burn before Smaug is just burn. Sequencing discipline: hold Blasphemous Act, Star of Extinction, and the self-damage instants until the dragon's down unless you're stabilizing for survival.
• Revel and Knuckles check at your upkeep — with an intervening "if." You need the count as your upkeep begins and again on resolution, and opponents get a full turn cycle to see it coming. Build the last few Treasures at instant speed on the end step right before your turn (Cut Propulsion, Deadly Dispute, Pestilence activations), and hold Swat/Bolt Bend for the Vandalblast-shaped response.
• The Pestilence loops hurt you too. "Each player" includes you — track the race, stop while your buffer holds, or run the loop under The One Ring's protection and take nothing. Fiery Emancipation triples your engine and your self-inflicted hits: 3 Treasures per activation, but 3 to your face too.
• Fiery Emancipation doesn't triple opponents' damage to Smaug — only sources you control. Redirected enemy burn mints face value.
• Xorn is per-event. A 20-Treasure trigger becomes 21, not 40. (Manufactor is the multiplier; Xorn is the tip.)
• Your wipes kill your crew. Blasphemous Act and Star of Extinction pay Smaug but kill Mayhem Devil, the drain creatures, and Face-Breaker. If the drain shell is doing the winning, count what the wipe costs before cashing it — or wipe first and rebuild from the pile.
• Smaug's own combat damage makes nothing. An 8/7 flier is a fine clock, but if a swing and a Cut Propulsion are competing for the turn, the instant usually pays better.
