We don’t have decent scans of Nissa yet, so here’s the gist: She’s basically a worse version of Civic Wayfinder (less usable creature class types and can only find forests), but if you have seven lands in play, she flips. The planeswalker version reveals cards of the top of your library. If its a land, you get to play it immediately, otherwise you put it into your hand. The -2 ability produces a legendary 4/4 elemental and the ultimate ability makes six of your lands 6/6 elemental creatures.
Again, some thoughts on the deck and a tournament report from an FNM.
