Eq metagross
So heatran double resists steel, and super effects with fire moves, but is double weak to ground. If before people weren't using earthquake on metagross to counter cover in PvP, I have a feeling we're going to see that happening very soon.
Not to mention eve in raids, Eq metagross out DPS's machamp because double weakness to ground, though theres many better options than both against heatran, could be fun against BB/SE or IH raids.
