Flurry of Blows

Your Commander is a Monk in addition to its
other types. Monks you control have Prowess.
(Whenever you cast a noncreature spell, this creature
gets +1/+1 until the end of turn.)
Whenever a Monk you control deals combat
damage to a player, you may draw a card. If you
do, discard a card.
