lel, first time trying this.
Maybe Heatran?
It resists / is immune to everything Altaria is weak to, and can hit back hard against them. With access to lava plume to take care of Scizor, Magnezones, and Ferrothorns, and Earth Power to take care of Poison types, it can take care of everything Altaria is weak to. It even has Flash cannon for other fairy types that Altaria is weak to.
