Symbiotic Wurm

Fourteen total power and toughness for eight mana, but the distribution is the whole point: a 7/7 that, when it dies, leaves behind seven 1/1 Insects spread across seven bodies. Killing the front half does not solve the problem; it converts one big target into a wall, a trade single-target removal hates to make. The seven tokens are the real text; the Wurm is the delivery mechanism that has to die first. This is green's old answer to the question of how to make a fat creature resilient without bolting on a keyword soup of protection: don't shield the body, make killing it expensive. The design predates the explosion of token-payoff and aristocrat shells that would later turn a one-card-into-seven-bodies death trigger genuinely threatening; in the years after this kind of card first appeared, it was largely a big lump that left a mess when it fell. To a sacrifice or anthem strategy, it offers a pile of fodder pre-attached to a serviceable beater, so the eight mana buys both the front-half attacker and the back-half engine fuel in a single slot. The math rewards both ends: trade it into combat and the swarm replaces it, or feed it to something that wants a corpse and get seven bodies instead of one.
