Corrupted

Cards with the Corrupted ability word from Phyrexia: All Will Be One, which gates a bonus effect behind the threshold of an opponent having three or more poison counters. Skrelv's Hive grants lifelink to toxic creatures once corrupted, Vivisection Evangelist destroys a creature or planeswalker on entry while corrupted, and Contaminant Grafter draws a card and plays a land at end step under the same condition. Narrower view of poison.poison_synergy, the broader grouping for any card that scales with or enables poison counters; this entry is specifically the subset whose rules text uses the Corrupted threshold trigger, not generic toxic dealers, infect creatures, or proliferate enablers.
