Teddy, Elderwood Warrior

If Teddy, Elderwood Warrior is in the command zone as you start the game, you may search your library for a Forest and put it into the command zone. For the rest of the game, you may play that land.
Whenever you cast a spell with X in its mana cost, you may put X +1/+1 counters on target land you control. It becomes a 0/0 green Elemental creature with haste.
