One thing I'd like to ask in regards to people's sets on here:
Why is there any justification for giving Tentacruel Leftovers over Black Sludge?
- Black Sludge means Lefties can go to another teammate and not break the Item Clause
- Black Sludge is beneficial only to Poison-type Pokémon, so if it's Trick'd/Switcheroo'd/Thief'd away, it'll be to that Pokémon's detriment (unless they happen to be a Poison-type, obviously)
Maybe I'm missing the point here, but for all Poison-types, Black Sludge > Leftovers (unless another Poison-type in the team is holding it obviously.)
