Eccentric Pestfinder // Turn Stones (SOC) (94) / Extended Art

Trample At the beginning of each end step, if you gained life this turn, this creature becomes prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.) // For each opponent, you create a 1/1 black and green Pest creature token with "When this token dies, you gain 1 life."
