Creatures you control get +0/+2 until end of turn.

Threshold — If seven or more cards are in your graveyard, choose a color. Creatures you control also gain protection from the chosen color until end of turn.

Nahiri's Warcrafting deals 5 damage to target creature, planeswalker, or battle. Look at the top X cards of your library, where X is the excess damage dealt this way. You may exile one of those cards. Put the rest on the bottom of your library in a random order. You may play the exiled card this turn.
