Alibou, Ancient Witness — Legendary Artifact Creature — Golem (4/4)

Other artifact creatures you control have haste. Whenever one or more artifact creatures you control attack, Alibou deals X damage to any target and you scry X, where X is the number of tapped artifacts you control.

Oracle confirmed (commander_oracle_ok = true). Important correction to the scout’s brief: X is the number of TAPPED ARTIFACTS you control, NOT the number of attacking creatures. This changes how you build and pilot:

  • Every tapped artifact counts — tapped mana rocks, tapped artifact lands (Ancient Den, Great Furnace, Rustvale Bridge), tapped Clue/Treasure/Food tokens, and any artifact creature that’s tapped (from attacking, crewing, or activating). You want a board full of artifacts and you want them tapped when the trigger resolves.
  • Because attacking taps your artifact creatures, a wide artifact swing naturally taps a big pile of artifacts. Add tapped mana rocks and artifact lands on top and X balloons.
  • The ping is “any target,” so it doubles as reach to the face and as repeatable removal/inevitability.

Gameplan

Boros artifact go-wide. Flood the board with cheap artifact tokens (Thopters, Servos, Golems, Myr, Robots), give them haste via Alibou, and swing. The attack taps your artifact creatures; combined with tapped rocks and artifact lands, Alibou throws a fat chunk of damage at a face or a problem creature every combat and scries you deeper. The flyer-heavy token base (Thopters, Skyscanner, Inspiring Overseer, Oltec Cloud Guard, Propeller Pioneer) carries the evasive clock; the ground tokens crew Vehicles and feed the X count.

Inevitability comes from the ping, not from combat alone: even through blockers, every combat is a guaranteed burst of reach. Reckless Fireweaver pings each opponent for 1 whenever an artifact enters under your control; Spireside Infiltrator (a non-artifact Human Rogue) pings the active player’s opponents for 1 whenever it becomes tapped — which attacking does, so a swing fires it. Both stack passive, repeatable face-damage on top, so you bleed the table out even when your attackers get chump-blocked.

Key synergy lines

  • Tap-everything-then-swing. Float mana from your rocks before combat if you don’t need it — leaving rocks tapped raises X. Crew Vehicles (Sky-token bodies into Broadcast Rambler / Renegade Freighter-style crew) before the Alibou trigger; crewing taps the crewers (more X) and the Vehicle becomes a tapped artifact attacker too.
  • Artifact lands as free X. Ancient Den, Great Furnace, Rustvale Bridge, and Darksteel Citadel are lands that are also artifacts — tap them for mana in your main phase and they’re sitting tapped during your attack, each adding +1 to X for free. Four of them now, a small but real bump to the X count rather than the engine on their own.
  • Reckless Fireweaver loop. Every artifact you play (and every token that’s an artifact) pings each opponent for 1. With a board that spits out tokens off Golem Foundry, Myrsmith, Cogworker’s Puzzleknot, Camera Launcher, Mouser Foundry, etc., this is a slow drain that closes games the ping started.
  • Built to Smash / Mishra’s Onslaught as a finisher. Built to Smash gives an artifact creature +3/+3 and trample; Mishra’s Onslaught pumps the whole team +2/+0. A wide hasty board plus a pump spell plus a 6–10 damage Alibou ping ends a player out of nowhere.
  • Foundry Inspector + token engines makes your artifact spells cost less, snowballing the token flood and powering charge counters on Golem Foundry.

Role breakdown (with counts)

  • Lands — 36. 15 nonbasic + 11 Mountain + 10 Plains. The 15 nonbasics: 4 artifact lands that double as Alibou fuel (Ancient Den, Great Furnace, Rustvale Bridge, Darksteel Citadel), Command Tower for fixing, plus Boros duals/bounceland/cycling lands (Boros Guildgate, Wind-Scarred Crag, Boros Garrison, Secluded Steppe, Forgotten Cave, Drifting Meadow, Desert of the True, Desert of the Fervent, Abraded Bluffs, Alpine Meadow). Cycling lands (Forgotten Cave, Secluded Steppe, Desert of the True/Fervent, Drifting Meadow) turn into cards in the late game.
  • Ramp — 10. Sol Ring, Arcane Signet, Boros Signet, Mind Stone, Prophetic Prism, Guardian Idol, Fractured Powerstone, Manalith, Boros Cluestone, Alloy Myr. All tap, so every one is also a +1 to Alibou’s X. Alloy Myr is an artifact creature that gets haste and can attack or crew.
  • Card advantage — 11. Skyscanner, Inspiring Overseer, Novice Inspector, Thraben Inspector (Clue ETBs — Clues are artifacts), Workshop Assistant (artifact recursion), Chromatic Star, Implement of Combustion, Implement of Improvement, Energy Refractor, Candy Trail, Basilica Skullbomb. Scry from Alibou smooths on top.
  • Spot removal / interaction — 11. Lightning Bolt, Galvanic Blast (4 dmg with metalcraft — trivial here), Burst Lightning, Flame Slash, Fiery Impulse, Electrostatic Bolt (4 to artifact creatures), Firebolt, Chain Lightning, Divine Arrow, Swift Response, Pacifism. Plus Alibou herself is repeatable removal.
  • Pseudo-wipes — 2. Boiling Earth and Scouring Sands each deal 1 to each creature your opponents control — asymmetric in a deck whose own board is mostly flyers/tokens you’d rather keep. Kept low because a true wrath hurts a go-wide deck; the inevitability plan (pings + Fireweaver + evasive flyers) is the real “we win the long game” lever.
  • Payoffs / enablers — rest. Token makers (Ghirapur Gearcrafter, Cogworker’s Puzzleknot, Glint-Sleeve Artisan, Golem Foundry, Nimblewright Schematic, Camera Launcher, Master’s Call, Mishra’s Onslaught, Mouser Foundry, Circuits Act, Myrsmith, Filigree Crawler, Scrapwork Cohort, Iron League Steed, Sensor Splicer, Auxiliary Boosters, Broadcast Rambler, Oltec Cloud Guard, Propeller Pioneer, Inspired Inventor, Mouser Attack!), passive pingers (Reckless Fireweaver, Spireside Infiltrator), metalcraft beaters (Court Homunculus, Ardent Recruit), value bodies (Ornithopter, Foundry Inspector), and the team-pump finisher (Built to Smash).

Win condition

Evasive hasty artifact-flyer swarm closing the air, while Alibou’s combat ping (X = your pile of tapped artifacts) plus Reckless Fireweaver / Spireside Infiltrator passive drain grind the table down — inevitability through repeatable, scaling reach rather than one big alpha strike.

Pilot notes

  • Tap rocks and artifact lands in your main phase even if you don’t spend all the mana — leaving them tapped inflates X before you declare attackers. Float the mana into a combat trick if needed.
  • Sequence: develop board → main-phase tap rocks/artifact lands and play artifacts → declare a wide attack → Alibou triggers with a big X → point it at the scariest creature or the lowest-life player, scry the same number.
  • Crew Vehicles before combat damage but the crewers tap immediately, which is fine — they add to X. Don’t crew with a creature you wanted to attack unless the Vehicle hits harder.
  • Galvanic Blast and Electrostatic Bolt are near-free 4-damage removal here; hold them for problem blockers or to finish a creature Alibou softened.
  • Against a board you can’t punch through, lean on the air (Thopters/flyers) and let Fireweaver + Alibou’s any-target ping do the closing.

Weaknesses

  • Board wipes are the obvious nightmare for any go-wide deck. Mitigation: cheap recursion (Workshop Assistant, Scrapwork Cohort unearth), token engines that rebuild (Golem Foundry, Myrsmith, Camera Launcher), and the fact that even a half-board still produces a meaningful Alibou ping.
  • No true mass removal of opponents’ boards (commons-only Boros). The asymmetric 1-damage sweepers only clear x/1s; you rely on spot removal + the ping + racing.
  • Artifact removal (mass Disenchant effects, Vandalblast-style) hits both your rocks and your creatures at once — your X count and your board shrink together. Diversify a little into non-artifact bodies (the Human/Dwarf artificers) to hedge.
  • Mana base runs several tapped lands (artifact lands aside); a few too many tapped lands on the draw can slow the early token flood.
