Tavrian, Spring Eladrin

Tavrian enters the battlefield with a +1/+1
counter on it for each color of mana spent to cast
it.
When Tavrian enters the battlefield, you may
search your library for a land card, put it onto
the battlefield, then shuffle. If that land is a
Plains, Island, Swamp, Mountain, or Forest, you
may search your library for a basic land card, put
it onto the battlefield tapped, then shuffle.
{g},{t}: Add two mana of different colors.
