Nissa, Vastwood Seer // Nissa, Sage Animist
Legendary Creature — Elf Scout - (mythic)
When Nissa, Vastwood Seer enters the battlefield, you may search your library for a basic Forest card, reveal it, put it into your hand, then shuffle.
Whenever a land enters the battlefield under your control, if you control seven or more lands, exile Nissa, then return her to the battlefield transformed under her owner's control.
