Flatwoods Monster

At the beginning of combat on your turn, put a
+1/+1 counter on target creature.
{t}: Add {c}{c}. When you next cast a spell with
{x} in its mana cost or activate an ability with
{x} in its activation cost this turn, copy that spell
or ability. You may choose new targets for the
copy.
(A copy of a permanent spell becomes a token.)
