Coin flips are red's oldest design joke, and this is the version where the punchline can hit you back. Every upkeep hands you a Land Mine, a colorless token that punishes the ground assault you were already happy to see: it deals two damage to an attacking creature without flying for one red mana and a sacrifice, instant-speed removal you stockpile in advance. That points the card toward a defensive, grindy posture more than the aggressive one its tribe usually wants, and it points toward small attackers specifically, since the two damage finishes off the one- and two-toughness bodies but only chips a larger one. The catch is the flip that follows, and the catch is genuinely punishing: lose it and the engine deals two to a body that only has two toughness, so a single bad result wipes out the source of all those mines mid-game. That is the tension the design hangs on. The token generation is free and recurring, but the maintenance cost is variance applied directly to the thing generating value, not to a token you can afford to lose. It models a kind of red gambling the color rarely commits to so literally: you are not flipping for a spell's outcome, you are flipping for whether your permanent survives to flip again next turn. Stockpiling mines is a quietly elegant anti-aggro plan, but it requires the engine to keep winning a coin toss it loses half the time.
