It seems confusion is really getting a lot more focus on it than it has before. It's interesting, probably still one of the less useful status conditions, but still interesting. Once Parasect is out and the Tinnitus Bell I might try something. However, I think just using Parasect with the Tag Bolt Tentacruel, Nihilego GX, and Seviper (More Poison ability) would be at least a little more consistent.
Still, relying on residual damage from status is always less reliable than just straight up attacking with big numbers. I can't remember, are there any pokémon with "Hex" attacks that do more damage to defending pokémon inflicted with status in the current format?
