Whenever you cast your second spell each turn, you may sacrifice an artifact. If you do, flip a coin. When you win the flip, copy that spell. You may choose new targets for the copy. When you lose the flip, Breeches deals damage equal to that spell's mana value to any target.
Cast cheap, high-impact spells while keeping a steady stream of disposable artifacts to feed Breeches. Hit your second spell each turn, sacrifice a token or cheap artifact, and either copy the spell (heads) or fling its mana value as damage (tails) — both halves are upside. You grind value and burn until you assemble a spell-copy combo or simply burn the table out.
Every coin flip is win-win: a free copy or guaranteed damage to any target.
Coin-flip support and 'win/lose flip' payoffs turn the ability into broken value engines.
Cheap commander (MV 3) with menace that pressures life totals on its own.
Izzet's deep pool of cantrips, treasure makers, and copy spells fuels consistent triggers.
Heavily commander-dependent — without Breeches the deck stalls.
Needs both a second spell each turn AND an artifact to sacrifice, requiring careful sequencing.
Variance from coin flips without fixing cards can be frustrating.
Fragile in stax/removal-heavy metas; little board presence beyond the commander.
With infinite Treasures from copy loops it's a clean alternate win condition.
Add coin-flip doublers (Krark, Krark's Other Thumb, Okaun/Zndrsplt package) to make flips reliable and explosive, and cheap Treasure generators (Dockside, Jeska's Will) for free triggers. Lean into copy spells and X-burn (Fireball, Comet Storm) as copy targets, then tighten the mana base with fast rocks like Mana Crypt and Sol Ring to consistently double-spell early. Cap it with drain payoffs (Reckless Fireweaver, Marionette Master) and a tutor suite to find your combos.
