Repeal Infiriority

Repeal Infiriority costs {1} less to cast if it
targets a creature with base power 2 or less.
Target attacking or blocking creature gets +2/+1 until end of turn. Put your choice of
a +1/+1, first strike, or lifelink counter on it. Then, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)
