Caged Zombie

A repeatable drain that gates itself behind the one thing an aristocrats deck produces in bulk: a dead creature. The activation, and a tap, is cheap enough to fire on repeat, and the ability is untargeted, hitting each opponent for two, but the "activate only if a creature died this turn" clause turns the tap into a scoreboard for a sacrifice engine rather than a standalone burn source. The 2/3 body is doing quiet work here, because the card wants to survive to untap and fire again turn after turn, and the death condition is satisfied by fodder you were already trading away: tokens, chump blockers, anything fed to an outlet. The design lives entirely in that conditional. Detach it and you have a slow, overpriced life-drain nobody would run; bolt it onto a board that manufactures deaths and it becomes a slow bleed that closes games while your sacrifice pieces do the actual killing. It is a common-rarity payoff, connective tissue for the black attrition strategies that turn creature deaths into an incremental clock, and it asks nothing exotic in return: a creature dying, and the mana to pull the trigger. The floor is a fine blocker; the ceiling is two life a turn, every turn, off deaths you would trigger anyway.
