Sunrays Over The Forest

Split second
If you control at least three other piercers, this spell has flash.

Destroy target nongreen creature. If no creature was destroyed this way, Underpeirce X, where X is your devotion to green. (When you Underpierce, target red creature you control gains your choice of either double strike, shroud, flying, haste, menace, or lifelink until the end of the current or next combat step, whichever comes first.)
