Eccentric Pestfinder (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.)

Turn Stones BG

Sorcery

For each opponent, you create a 1/1 black and green Pest creature token with "When this token dies, you gain 1 life."
