not very $$ 1st turn win

If you control a Forest, rather than pay this spell's mana cost, you may have an opponent gain 3 life. Target creature gets +4/+4 until end of turn.

Search your library for a green creature card, reveal it, put it into your hand, then shuffle. At the beginning of your next upkeep, pay . If you don't, you lose the game.
