This THING is so freaking painful, the only time I was able to beat it in Shoddy is because I had a lucky incident. My opponent switched Wobbufet into my Gengar's Hypnosis... and since my Gengar did NOT know Shadow Ball, I had to use Thunderbolt. My opponent, thinking I'm using Shadow Ball.. switches into Gyarados, faints, leaves the game.
I tried using a Wobbufet once *gets shot* , and I've gotten in this REALLY bad situation that made me leave the battle.... just after switching in my Wobbufet, the opponent... apparently switches in HIS Wobbufet too. This was more painful than the time I got stuck in a Magnezone VS Magnezone war.
Anyways, I really do think Wobbufet is pretty uber. If it wasn't for his godforsaken Shadow Tag...
Safeguard is another story. You HAVE to predict your opponent into the status, or else its gg no status on Wobbufet.
Destiny Bond.. not too much of a problem at all since hes slow ^^
Encore.. now here's a very BAD thing for Wobbufet opposers and good thing for Wobbufet users... once locked in Shadow Tag, you might be Encored into something.. a Swords Dance since you really can't hurt Wobbufet.
The only thing I found that truly defeats this blob of crap is Taunt, but Wobbufet's switch in can be so disgusting that your Pokemon WILL be taken down one by one. By moving Wobbufet into the OU, they have given a new requirement for a team... a TAUNTER
