Enchantment - Quest
Once each turn, when you cast a spell with mana value equal to the number of lands you control, you may add a quest counter.
1, 2 — You may search your library for a basic land card, reveal it, then shuffle and put that card on top. You gain 1 life for each quest counter on Hoof Cliff Expedition.
3 — Search your library for a creature card, reveal it, put it into your hand, then shuffle.
