Chittering Skitterling⁣ - Phyrexia: All Will Be One⁣ (Uncommon)⁣ [87]

Chittering Skitterling allows you to draw a card by sacrificing an artifact or creature, but this ability only activates when an opponent has three or more poison counters. This mechanic synergises well with poison counter strategies, making it a valuable asset for decks that focus on infect or proliferate. However, its effectiveness is limited to the late game when opponents are affected by poison counters, and it requires careful timing to maximise its potential.
