Golrith, Sunset Stalker

Golrath, Sunset Stalker can't be blocked by
creatures with power less than or equal to the
number of nonbasic lands you control.
Roam - At the beginning of your upkeep if you
control three or more nonbasic lands with
different names, look at the top five cards of your library. You may reveal a land card from among
them and put it into your hand. Then put the
rest on the bottom of your library in a random
order.
