Satyr Kid

Whenever a source you control destroys an artifact or enchantment, you may mature Satyr Kid. (To mature this creature, exile it. If you do, search your library for a non-Young creature card that shares a creature type with it. You may cast it by paying the difference in mana costs between it and this creature. Then shuffle your library.)
"Revel up!"
