Cocoon (59) [Chronicles]

Enchant creature you control When this Aura enters, tap enchanted creature and put three pupa counters on this Aura. Enchanted creature doesn't untap during your untap step if this Aura has a pupa counter on it. At the beginning of your upkeep, remove a pupa counter from this Aura. If you can't, sacrifice it, put a +1/+1 counter on enchanted creature, and that creature gains flying.
