Goldbrick (You may pay {0} instead of paying any or all of the colored mana costs of this spell. If you do, the next spell you cast costs that much more, and until then, you can't cast spells using alternative costs.)
Target creature gets +1/+0 and prowess until end of turn. (It gets +1/+1 until end of turn per noncreature spell you cast this turn.)
