Nissa, Vastwood Seer // Nissa, Sage Animist

When Nissa enters, you may search your library for a basic Forest card, reveal it, put it into your hand, then shuffle. Whenever a land you control enters, if you control seven or more lands, exile Nissa, then return her to the battlefield transformed under her owner's control.

[+1]: Reveal the top card of your library. If it's a land card, put it onto the battlefield. Otherwise, put it into your hand. [−2]: Create Ashaya, the Awoken World, a legendary 4/4 green Elemental creature token. [−7]: Untap up to six target lands. They become 6/6 Elemental creatures. They're still lands.
