Conjuration's Incarnation

Storm (When you cast this spell, put a copy of it onto the stack for each other spell that was cast before it this turn. If the spell has any targets, you may choose new targets for any of the copies.)
As Conjuration Incarnation is on the stack, you may pay {r/w}. If you do, it resolves as a 1/1 Elemental creature with haste.
Gain 1 life for each creature that has entered the battlefield this turn.
