Raidan Sage

When any creature you control with "Raidan" in
its name dies, you may pay {u}{g}. If you do, put a
+1/+1 counter on target creature you control.
When a +1/+1 counter is put onto any creature
you control, proliferate, then gain life equal to
the combined power of all creatures you control.
When this creature is sent to the graveyard, draw
a card.
