Dondozo + Blissey Stall Core

by Hyper bol

Dondozo and Blissey are the two Stall staples of this generation. Dondozo deals with (almost) every Physical Pokemon of the tier, while Blissey walls (almost again) every Special-based Pokemon in OU. The set will usually be the same is every Stall team, but you can have different option. On Dondozo, you can use Fighting tera if you already have an Ogerpon counter. Liquidation is replaceable by Waterfall which has more PP, or Avalanche which hits Dragon and Flying Types. On Blissey, you can use a Dark tera if you already have a Walking Wake counter and you are weak to Pokemon with Stored Power or Psyshock. Fairy Tera allows you to wall Mixed Dragapult. Shadow Ball over Seismic Toss hits Ghost-Types. You can run Protect over Stealth Rock if you already have a Stealth Rock Setter, which improves the Future Sight Match'Up.
