I am actually incredibly impressed by Zangoose' sheer power after doing some calcs. 252/0 Cofag is ohko'd by +2 Shadow Claw, Gligar is ohko'd by +2 Facade (!) and by extension so is literally every other physical wall in the tier that is neutral to normal attacks (Slowbro, Suicune, etc). The biggest problem is choosing between whether you want to hit ghosts, rocks and steels, or prevent revenge killers from having an easy time. Zangoose' Quick Attack is pretty powerful at +2, so it's definitely an important contender, especially when you realize that +2 Adamant Quick Attack has a 50% chance of ohkoing Scarfcross after SR. Speaking of that, Adamant v. Jolly is actually a pretty important decision. Facade definitely doesn't need any more power, but Quick Attack definitely does, as does its coverage.
Zangoose could be pretty intriguing as a dedicated stallbreaker / late game cleaner. I'll have to try it.
Everything was beautiful. Nothing hurt.
I'm back, baby. Look for me in 5th gen UU!
