Clutch of Undeath

Two cards in one shell, sorted by a single keyword on whatever the Aura lands on. Read the type line of the target and the card resolves into one of two opposite functions: a +3/+3 pump if that creature is a Zombie, a -3/-3 shrink toward the graveyard if it is anything else. That conditional split is the tribal-payoff design that defined the era when creature types first carried mechanical weight: the reward fires only when the type lines up, so the same printing reads as a removal spell against the field and a combat buff at home. The wrinkle in the split is who the buff serves. The +3/+3 attaches to any Zombie, friend or foe, which means against a Zombie deck the card loses its removal function entirely: point it at an opposing Zombie and you have spent five mana to make their creature bigger. As removal it carries the standard Aura tax: it whiffs if the target leaves before it resolves, it can be undone by a bounce, and the -3/-3 leaves four-toughness creatures standing where a hard-removal spell of the period would still kill them. As a buff its ceiling is tied to having Zombies to enchant, a tribe black has been building around for decades. The result is a card whose worth is dictated by what sits across the table rather than by its rate, and one that quietly inverts against the very decks it most resembles.
