Land creatures you control get +1/+1 and have vigilance.
Whenever you cast an instant or sorcery spell
by paying its mana cost, you may pay {x}{g/w}. If
you do, put X +1/+1 counters on target land
you control and it becomes an 0/0 Elemental
creature with haste as that spell resolves. It's
still a land.
