Just like the normal form, Deoxys attack form is also psychic. As the name suggests, the attack form's attack increases 345 → 414. In return, the defense lowers 115 → 46. The stamina/HP doesn't change. So how does this change the rankings? Not much. But with such a large drop in defense, the DPS increases tremendously and this Tier 5 raid can be solo'ed. The list of top DO@20 counters for Deoxys (attack form) are:
- Tyranitar: Bite, Smack Down / Crunch
- Weavile: Feint Attack, Ice Shard / Foul Play
- Mewtwo: Psycho Cut, Confusion / Shadow Ball
- Houndoom: Snarl / Foul Play, Crunch
- Shiftry: Feint Attack / Foul Play
- Muk Alola: Bite / Dark Pulse
- Honchkrow: Snarl / Dark Pulse
- Scizor: Fury Cutter / X-Scissor
- Absol: Snarl / Dark Pulse
- Gardevoir: Charge Beam / Shadow Ball
