I have an idea for a new keyword ability called scavenger. To activate it, tap a creature with it and target a nonartifact, non-Spirit creature from any graveyard. Put an amount of bite counters on the targeted (scavenged) creature equal to the scavenger’s power or the scavenged creature’s toughness minus how many bite counters it has already, whichever is lower, and that many +1/+1 counters on the scavenger. If a creature has an amount of bite counters equal to its toughness, exile it.
