7 Star Pikachu Loses in 4 turns SOLO

WARNING: This is RNG reliant! This is NOT intended to be a consistent and/or SOLO farm. For more advanced raiders with patience :)
The fastest solo in terms of number of turns actually goes to Venusaur! With 3 acid sprays, an arboliva npc, and petaya berry; Frenzy Plant is gg
PERMANENT NPC teammates: Arboliva required and any intimdator; third option can be anyone but Gardevoir who would mess up overgrowth activating.
Venusaur lvl 100 @ petaya berry
Nature: Rash ALL HYPER TRAINED
EVs: 252 Sp ATK l 252 Sp DEF
-Acid Spray
-Frenzy Plant
If you wanna play it safe, switch your nature to "modest"; do three acid sprays, an atk cheer, and then frenzy plant :)
