Incubation Pod

{1}, {T}, Exert Incubation Pod: You may remove a counter from any number of permanents you control. If you do, search your library for a creature card with mana value equal to the number of counters removed this way, put it onto the battlefield tapped with a stun counter on it, then shuffle. Activate only as a sorcery. (An exerted permanent won’t untap during your next untap step.)
