Strategy
Urza, Lord High Artificer — mono-U artifact combo (cEDH)
Gameplan. Deploy Urza plus a dense rock/Mox suite, then convert Urza’s “tap your artifacts for {U}” engine into one of three semi-independent infinite-mana loops. Cheap tutors (Trinket/Tribute/Trophy Mage, Fabricate, Whir, Reshape, Transmute Artifact, Tezzeret, Merchant Scroll, Mystical Tutor) assemble the two-card cores; a wall of free counters (FoW, Force of Negation, Fierce Guardianship, Pact, Mental Misstep) plus cheap protection (Flusterstorm, Swan Song, Spell Pierce, Offer, Counterspell, Spell Snare, Consign to Memory) shields the turn you go off. Winter Orb (lands-only; you float mana and win in a single untap) buys tempo asymmetrically since your mana lives on rocks, not lands.
Infinite-mana lines (all present, instant-speed on-plan):
- Isochron Scepter + Dramatic Reversal + rocks producing ≥{3} → infinite mana + infinite Reversal storm.
- Basalt Monolith + Power Artifact (untap cost drops to {1}, taps for {3} → net +2), or Grim Monolith + Power Artifact → infinite colorless.
- Grand Architect + Pili-Pala → infinite mana of any color.
Outlets / closes:
- Walking Ballista (universal lethal; Trinket-Mage/Fabricate-tutorable, Academy-Ruins/Emry recurrable) — hard kill for any infinite-mana line.
- Blue Sun’s Zenith → Thassa’s Oracle — deck a player or empty your own library into an Oracle win; BSZ shuffles back so it’s a repeatable draw/deck-out even without infinite.
- Aetherflux Reservoir — second, combo-independent close: Paradoxical Outcome + cheap-rock replays storm your life total to 50 and blast the table; it also instantly cashes any infinite-mana loop, so the deck no longer dead-ends if Ballista is exiled.
Grind plan. Urza’s {5} card-advantage activation, Mystic Forge / Sensei’s Top / Sapphire Medallion draw-loops, Rhystic Study, Mystic Remora, Vedalken Archmage and Paradoxical Outcome refuel through counter wars; Narset shuts off opposing card advantage in Rhystic/BSZ mirrors. Urza’s Saga chapter III fetches a {0}/{1} artifact (Sol Ring, a Mox, Lotus Petal, or Ballista) straight to the battlefield.
