But that opponent barely made any sense. EQ Roob? Psychic on something immune to it? Lolwut? Swagger is also too gimmicky, as it relies on the opponent hitting himself in confusion than killing you outright and spamming that free SD.
Roob gets walled by the likes of Croagunk without EQ, so it's not an awful choice. Psychic was a LOL moment, which i'd put down to the Sub messing with his head a bit.
Swagger IS a gimmicky move, no doubt about it (duh), but like all gimmicks it can be annoyingly effective in the right hands, and sans Own Tempo can the combo has the potential to kill anything. The thing is, nobody likes Confusion, especially not when they know they can eliminate themselves in one turn, so it can force switches and generally ruin any momentum the opponent has, and that can be a valuable thing outside of just type-based counters. As for the free SD - as I said being able to use it
properly usually needs decent priority or Unaware on your team, in which case your Swaggery gimmick is forming one part of a larger team. Keep in mind that Priority Subs and Priority Recover are extending a Swaggery user's longevity. Also keep in mind Special Attackers aren't going to be enjoying Swagger at all. Trickery is generally a superb move on its own, too.
That being said, may as well take the gimmick all the way. brb making a team of a 6 Swagger users.
