Card Rulings
9/20/2016 The set of creatures affected by Nissa’s last ability is determined as the ability resolves. Creatures you begin to control later in the turn and noncreature permanents that become creatures later in the turn won’t get +5/+5 or gain trample.
As for playability this might work in Titania EDH decks and casual land-centric standard decks with things like Gitrog etc. I hope that intro deck will be easily upgradeable so new players won't have miserable time playing with random cards they got at prerelease or in box they bought. Personaly I'm more interested in seeing the cards from intro decks interacting with planeswalkers.
