With great bulk and Power Spot, Stontank is a strong enabler that can let many offensive Pokemon hit even harder. Power Whip is its strongest STAB, while Rock Slide deals reliable spread damage. Wide Guard protects your team from spread moves, while Body Press hits off its huge Defence stat. The EVs maximise Special bulk, letting it make the most of both stats.
Pairs well with: Magikite, Wizareetin, Kolbolt, Mauycacque, Cthualauder, Eeryester
