Monotype is a fun metagame because you can sweep ordinarily meta Pokemon with Pokemon that would have no business keeping up with them.
Case in point: Choice Specs, Compound Eyes Galvantula on a Mono Bug Team.
I checked a damage calculator, no matter what the other guy said about the game ending with Toxapex, Galvantula was guaranteed to OHKO it with Thunder after Stealth Rock damage.
However, I will concede that if Thunder missed the Toxapex would've walled me and I probably would've lost.
