u need a focus sash

Blissey with Toxic? anyone tried?

Okay, Sturdy+Bulldoze Geodude works fine. I beated him with this + 2 Thunderbolts from Manectric with 185~ speed.

Guild ally let me borrow a 100 Azu using Play Rough - 1 hit.

 

Thanks for all the suggestions. Hope this helps someone else in the future, too.

I beat it with a lvl 98 gardevoir, 2x calm mind > 1 psychic

One focus sash on my lv96 Swampert and Deo was dead.

revives 1.5k each, focus sash.. like 25k? with focus sash its cleaner.. but idk. the houndoom's idea its the best I think by now. since he has pshychic, knock off, energy ball and ice beam.

 

dont try to outspeed its just almost imposible.

Use cottonee prankster to attack first with stun spore to paralyze deoxys
