Rose Blood Offering

Multikicker {p/w}{p/b} (You may pay an additional {p/w}{p/b} any number of times as you cast this spell.)
Put a +1/+1 counter on target creature you
control. It gains protection from the color of
your choice until end of turn. Then, Proliferate
for each time Rose Blood Offering was kicked.
If Rose Blood offering was kicked more than
three times, creatures you control get -5/-5
until end of turn.
