Flint, Woodland Thief

Menace
Whenever Flint, Woodland Thief deals combat
damage to a player, exile the top card of that
players library face down. You may play that
card for the rest of the game. You may spend mana
as though it were any color to cast it.

When you cast a card from exile, put a +1+1 counter
on Flint, Woodland Thief.

"Paws up, let's see what you got."
