Crowding Summit

({t}: Add {w} or {g} to your mana pool.)
Crowding Summit enters the battlefield tapped.
{2}{w}{g}: Create a 1/1 white and green Kor creature token. Then, if you control six or more Kor creatures, Crowding Summit becomes a 3/3 Elemental creature with lifelink and trample until end of turn.
Solace and serenity, sanctity and salvation.
