Getting swept by a Flying Gem Unburden Acrobat Drifblim was ... interesting.
I'm not sure if it says more about my team or the Drifblim.
That's pretty clever, actually.
If it makes you feel better, my Life Orb Walrein has netted me some wins today:
Walrein @ Life Orb
Modest, Thick Fat
255 HP/255 Sp. Atk (I was lazy, okay?)
-Ice Beam
-Surf
-Hidden Power (Electric)
-Encore (I'm going to try replacing it with Hail)
Somehow, it works extremely well; it takes down Pokemon that I need to take down in order to win the battle. I do not know what, exactly, you would call this... thing. It's certainly not a sweeper, but definitely not a Stallrein. It's a tad bulky, but its typing sucks too much to be a bulky water. I'll go with, "An Abomination Made by a Lunatic", or "Aambal" for short, because I don't think this is how you're supposed to use a Walrein.
Random Singles is pretty fun, I have to admit, even if I'm half-trolling with that Walrein. Mostly competent opponents, and there seems to be more and more English-speakers coming on, which is good. I'm probably going to be playing Pokemon Black for a long time thanks to Random matches.
