Melee Fox

Haste, first strike
{3}:This creature becomes a 6/6 and gains flying.
Put a fly counter on this card. If this creature
would die with a fly counter on it, instead take
the fly counter on this creature and it becomes a
3/3 and loses flying. Put three rebuild counters
on this creature. At the beginning of your
upkeep, remove a rebuild counter from this
creature. When there are no rebuild counters on
this creature, you may use this ability again.
