>>52846545NTA, but thought it would be fun to join in on the theorycrafting. Since Simple Beam is unavailable, could something like this work? I think Cinderace’s attacks and Fling both proc Weak Armor.
Armarouge-1 @ Weakness Policy
Modest Nature
Ability: Weak Armor
252 HP / 252 Sp Atk EVs
- Stored Power
Armarouge-2 @ Anything
Bold Nature
Ability: Flash Fire
252 HP / 252 Def EVs
- Acid Spray
Armarouge-3 @ Petaya Berry
Bold Nature
Ability: Flash Fire
252 HP / 252 Def EVs
- Fling
Indeedee @ Anything
Bold Nature
Ability: Psychic Surge
252 HP / 252 Def EVs
- Helping Hand
Strategy
- Wait for an attack from Cinderace, which will give Armarouge-1 -1 Def and +2 Spd due to Weak Armor (this needs to be before Fling, otherwise Armarouge-1 will already be at -1 Def and may not survive)
- Armarouge-2 uses Acid Spray on Cinderace
- Armarouge-3 uses Fling on Armarouge-1, activating Weakness Policy, Petaya Berry and Weak Armor. After Cinderace’s attack, this Armarouge will have +2 Atk, -2 Def, +3 Sp Atk and +4 Spd
- Indeedee uses Helping Hand on Armarouge-1
- Armarouge-1 uses Stored Power on Cinderace
