Wiggler

When Wiggler takes damage, put three time counters on it. Its base power/toughness is
4/4 until there are no time counters remaining. At the beginning of your upkeep,
if Wiggler has taken no damage since your
last upkeep, put a metamorphosis counter on Wiggler. If Wiggler has 5 or more metamorphosis counters, Wiggler has flying.
