Arayani, the Rising Oasis

Land creatures you control have trample, lifelink, flying and indestructible.
Awaken 6—{w}{u}{g}{7} (If you cast this spell
for {w}{u}{g}{7}, also put two +1/+1 counters on
up to three target lands you control. Each land targeted this way becomes a 0/0 Elemental creature with haste. It's still a land.)
