>>56455409>>56455421I used poison stall with Potent Toxin 2 to add 2 increments of chip, so the center takes 3% damage per Pokemon move while the sides take 30% damage per. So I had to last through 34 hits from the center and 4 hits from each side, which was done through high SpDef, passive healing, and screening. The tricky part was that the stage parameter increases the additional chances of move effects, so I had to outplay all of the enemy's move effect options given they were bound to occur during the battle.
