Yeah, Poison / Dark has only one weakness, but i think you're forgetting that Poison Heal doesn't work on Poison Types as they are immune to being poisoned (unless the opponent runs abilities like Corrosion).While many people prefer a normal defensive set, I tend to use the ultimate Stallbreaker. Chansey comes in, thinking it can completely wall it, when I click Whirlpool, imagine the horror on his face. Of course it can’t do much to Magic Bounce Chansey, but it still beats every non-bounce stall team. Oh yeah, Poison / Dark has 1 weakness so it’s hard to break.Tapu Fini @ Toxic Orb
Ability: Poison Heal

IVs: 0 Atk
That’s everything for now, but I sure had fun making these sets, and I had fun playing it as well.
Anyways, I have updated the LC AAA VR, though only a less change.
Some Added Abilities
Also, i could see some potential Unaware mon might struggle due to many wallbreakers might 2HKOed them, some also don't have access to a reliable recovery.
