Wishiwashi gx has a retreat cost of 3.
If mount lanakila was the active stadium, it would make wishiwashi gx retreat 4 instead.
If it then had body building pads attached to it (it adds 50hp to Pokemon with 4 retreat cost) would it benefit from the health increase?
I know it's not very competitive sounding, but it is amusing to think of.
If you put this with 3 other baby washi from dragons majesty you would make your GX have around 320hp with pads attached. hahaha
That would be crazy.
If any fellow judges or official members would like to chip in to answer, I'll come back with another wild idea.
