This is an early analysis, this may be dated or low effort

Drakloak is a very niche pokemon, but has some advantages. It's weaknesses are unfortunate, but it has the niche of being the only spin blocker in the month. It also has a very solid speed tier, making it a solid fast support option. Cursed body is good if you want to cheese a Drakloak predict, but overall Infiltrator is more consistent and helps status through sub. Choice band is also a set, but is usually much worse due to being hard to fit and not having any good stab options.
