Enchantment - Quest
(Add a quest counter as this enters. Sacrifice after 6.)
Whenever a land enters the battlefield under your control, add a quest counter.
1, 2, 3, 4, 5, 6 — Reveal the top card of your library. If it's a land card, put it into your hand. Otherwise, you may put it into your graveyard.
Until end of turn, creatures you control get +5/+5 and gain vigilance, trample, and haste.
