Terraform 8 (When this card enters the battlefield, put 6 +1/+1 counters on it and it becomes a 0/1 elemental with haste. It's still a land.)
Elemental creatures you control get +2/+2, have trample and indestructible, and have "{r/g}, {t}: Deal 1 damage to target creature or player. Put a +1/+1 counter on target elemental you control."
