Choose target creature you control and target creature you don't control. The creature you control gets +2/+1 until end of turn if it's a Knight. Then those creatures fight each other. (Each deals damage equal to its power to the other.)

Equipped creature gets +2/+0.

As long as it's your turn, equipped creature has first strike.

Equip (: Attach to target creature you control. Equip only as a sorcery.)
