Baal, Plane of Euthymia

This spell costs {X} less to cast, where X is the
total power of creatures you control.
At the beginning of combat on your turn, choose
a kind of counter at random that Baal doesn't
have on it from among flying, first strike, deathtouch, hexproof, lifelink, menace, reach, trample, vigilance, and +1/+1. Put a counter of
that kind on Baal.
"Then, while things are still good, let us have stillness...
Let us march towards Eternity."
