Alkas, Hidden Safehold

{t}, Add {c}{c}. Each opponent may put a land card from his or her hand onto the battlefield.
At the beginning of each opponent's untap step,
if that player controls at least five lands, that player gains control of Alkas and untaps it.
Luck: land (At the beginning of your upkeep, you may shuffle your library and reveal the top card of it. If
that card is a land, put it into your hand.)
