Skrelv's Hive

A slow, self-damaging engine that spends life now for a poison clock later. The upkeep drip pays out one Phyrexian Mite a turn, each a 1/1 with toxic 1 that cannot block, and that restriction is the tell: this makes attackers, not defenders, so the life loss compounds if you fall behind on the very board you built. The card flips character once the corrupted clause activates. With an opponent already sufficiently poisoned, every toxic creature you control gains lifelink, and the drain that was bleeding you out reverses into a life engine that outpaces the upkeep tax. That is the structural bet: a liability while the plan is still assembling, an accelerant once the early poison has landed and turned the conditional on. It rewards a board already committed to the toxic route rather than one trying to establish that route by itself, since a lone Mite per turn is a very gentle way to build up counters. The corrupted mechanic here does the same conditional-upgrade work that threshold or delirium do in other colors: a free rider stapled onto an ability that only matters once a resource count clears a line, tuned so the payoff arrives exactly when a poison-forward board has done its job.
