Rate the USUM totems on their difficulty:
>Raticate
Kind of tough compared to the other battles, but still not that bad.
>Aquaranid
Probably the second toughest totem. Electric berry really threw me off.
>Marowak
Pretty powerful but there's a trick. I recommend stealing it's thick bone with a fast mon.
>Lurantis
Didn't have too big of a problem because I had Fetchlander. Kecleon was tougher IMO.
>Togedemaru
It's the hardest one for me, but by hard I mean longest. My Magneton can't do much to it, and Togedemaru and Skarmory can't do much to my Magneton either.
>Mimikyu
It's one of the easiest one for me. Magneton -> Steel Z-move -> Dead Mimikyu
>Kommo-o
Another easier one. Flying Z move didn't take it out in one though. But it's still pretty easy.
>Ribombee
Having a steel or fire type makes this fight easy. Though if Blissey used heal pulse on Ribombee during my fight, it would've been a lot tougher.

I didn't black out in any of them. And Magnezone is the true MVP for all my totem battles.
