Churched

Target creature you control fights target creature
an opponent controls, if your creature survives it
gets plus +2/+0 until end of turn unless it is a Kingsman then it gets +2/+1 until end of turn
instead. Repeat this process until either your
opponent has no creatures or your creature dies,
except you must target the same creature that you control each time.
Hail Satan, and have a lovely afternoon madam.
