Breeches, the Blastmaker

Coin flips in Magic are usually flavor: a randomizer that trades reliability for a splashy payoff, tolerated because the payoff is fun rather than because it is good. What separates this Goblin Pirate from that lineage is that both sides of the flip are wins. Cast your second spell, feed an artifact into the barrel, and the coin resolves into either a full copy of that spell (new targets included) or a bolt scaling to its mana value at any target. Copy a removal spell and you have killed two things; lose the flip and you have still dealt meaningful damage to the same board. The variance is real, but the floor is a face burn effect and the ceiling is a doubled spell, so the deckbuilder is not choosing between good and bad outcomes so much as between two flavors of value. The artifact sacrifice is the cost that keeps the trigger from being free, and it pushes construction toward a supply of expendable artifacts to fuel the ability turn after turn. The second-spell condition ties it to a spell-density plan: this wants a hand of cheap interaction and cantrips, not a curve of standalone threats. Menace on a 3/3 is almost incidental, a way to keep pressure on while the real engine spins in the second main phase. It is one of the rare coin-flip designs built so the randomness decides which reward you get, not whether you get one.
