Kicker {3} (You may pay an additional {3} as you cast this spell.) If Moss-Pit Skeleton was kicked, it enters with three +1/+1 counters on it. Whenever one or more +1/+1 counters are put on a creature you control, if Moss-Pit Skeleton is in your graveyard, return A-Moss-Pit Skeleton from your graveyard to your hand at the beginning of the next end step.
