Re: [Deck] Updated: R/G/W Zoo
With Grunt you can't be aggro. If you play it Turn 2 he won't survive long enough to push damage through opponents defenses. He is a good lategame card, a gamestate Zoo is not willing to reach. Grunt could be a decent sideboard option against decks that fill the yard fast (Loam, Dredge). The only question is - do you need SB material against those decks?
