How can I tell what size Pumpkaboo/Gougeist is? I don't want to mistake it for a different size. And is there a way to breed or catch a certain size?
If you've only ever caught one, then your Pokedex will only register that size (I think). However, the other bet is to catch multiple that you think are differently sized and just compare them side by side.
So with Pain Split unavailable, what set would you recommend as a set until then on Rotom-W
Well, it depends on what you want the Rotom to do. I think a fun set might be a Trick Scarfer, where you run something maybe like:
Timid Rotom-W @ Choice Scarf
Trick
Hydro Pump
Volt Switch
Hidden Power/Thunderbolt/Thunder Wave/Will-O-Wisp/whatever tickles your fancy.
Where you hold on to your Scarf to keep a surprise boost of speed that might give you an advantageous hit, and once its served its purpose you Trick the Scarf away to hopefully cripple a supporter Pokemon.
What does a flawless breed mean? 6 31 IVs, or does it mean when you get 5 31 IVs?
I think it can mean both things. I've heard people refer to 31/31/31/x/31/31 as flawless since Special Attack is irrelevant, but I guess it depends on the person using the term.
Is there a thread/post somewhere about a good battle maison team?
There is a
thread for discussion over at Orange Islands.
I haven't been able to test myself, so does anyone know if becoming Electric type after being Paralysed removes the Paralysis?
It does not. Pokemon that become Poison, Steel, and Fire types remain poisoned and burned as well.
