>>47149083AssVest is a fair point, although I would much rather be sure I'm underspeeding mirror matches, Call me paranoid.
Tran is a nice point, but is the only mon I'd switch into, which is known to run taunt.
My main gripe was flip turn seeing counterplay in the shape of switch-ins, while teleport is effectively riskless when it comes to switch-ins. I might be grasping, but the ability to waste the opponents protect, so that your breaker is on much less of a timer when statused is a godsend and all to common in stall matchups.
I won't deny flip turn being a good move at all, it's great, but chances are the meta will adapt to it, especially when it is coming from a rank S mon.
The possibility of it being countered via switch-ins is reason enough for me to prefer teleport over it.
