Wild Magic Rage

At the beginning of combat on your turn, reveal
the top card of your library, then place it into
your hand. If the revealed card is green, put two
+1/+1 counters on enchanted creature. If the
card is red, deal 3 damage to any target. If the
card is blue, enchanted creature cannot be
blocked this turn. If the card is colorless, pick one
option.
"Yeah, I might've killed civilians that one time."
"What do you mean, might've?!"
