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