Flesh Thieves

Defender, Trample
When Flesh Thieves enters the battle Field, you
may put any number of -1/-1 counters on
creatures you control, for each -1/-1 counter put
on a creature this way, put a +1/+1 counter on
Flesh Thieves.
If Flesh Thieves has three or +1/+1 counters on
it, it can attack as though it did not have
defender.
And wherever you go, never go into the forest without leaves, I fear for any that do.
