Polikoros, Nature's Nurturer

Lifelink
Whenever you gain life for the first time each
turn, if you control less than ten lands, search
your library for a basic land card, reveal it and
put it into your hand. Shuffle your library.
{2}{g}{w},{t}: Target land you control becomes a
3/3 Elk Spirit creature with lifelink and haste.
It's still a land.
