Titania, Gaea Incarnate

Vigilance, reach, trample, haste
Titania, Gaea Incarnate's power and toughness are
each equal to the number of lands you control.
When Titania enters the battlefield, return all land
cards from your graveyard to the battlefield tapped.
{3}{g}: Put four +1/+1 counters on target land you
control. It becomes a 0/0 Elemental creature with
haste. It's still a land.
