Carnage, Crimson Chaos

The reanimation clause is engineered to give with one hand and take with the other: the creature you drag back arrives on a leash and a fuse. It must attack every combat, and the moment it connects with a player it sacrifices itself, which reshapes what looks like a two-for-one into a single-use missile. The choice to cap the target at mana value three or less is the tell: the payoff lives in enters-the-battlefield triggers and dies triggers on cheap value creatures, not in a durable body you would want to keep. Bring back a creature for its arrival effect, force it into combat, and the death trigger fires once it lands a hit or once the opponent trades with it in blocks; you never get to park it as a permanent blocker and pocket the extra creature. Note the wrinkle in the fine print: the self-sacrifice only fires on combat damage to a player, so a chump-blocked attacker survives the swing and is compelled to attack again next turn, still on its leash. Mayhem gives the villain a discounted cast for the same black-red price as its keyword cost, another route onto the battlefield alongside a hardcast. Trample on the 4/3 keeps it relevant as a clock even when the reanimation half whiffs. The whole shell commits hard to graveyard-as-resource: it wants creatures in the yard worth reanimating and converts a fair board into a compressed, self-consuming burst of aggression rather than a lasting one.
