I have decided on
Fire-Flarewolf
Water-(other than king pen)
Earth -(other than gq)
Life-Boom Bloom
Air-Wildstorm
Tech-
Undead-
Magic-
Light-Blaster Tron
Dark-already have Starcast

I wanna access all realms and try to get one of each class too. ☺️

Well I've already been planning...
Aurora
Starcast
Ambush
Ro-Bow
Air Strike
Tidepool
Flarewolf
Mysticat
Chopscotch
Barbella

And unless you're willing to have a few villains here and there, that's the only way to get all the Battle Classes and Elements with just 10 Sensei

if you want as few as possible; wolfgang, tidepool, barbella, pain-yatta, chain reaction.
me personally, I just go with every villain (including grave clobber).

You have two Knights and Ninjas, so... If you want to get one per Class, change Starcast for Hood Sickle and Blaster-Tron for Aurora. Wolfgang for Undead/Bowslinger, Tri-Tip for Earth/Smasher, Mysticat for Magic/Sorcerer, Dr. Crankcase/Dr. Neo Cortex for Tech/Quickshot and Grave Cobbler for Water/Brawler.

Sounds good?

I've pretty much decided on getting the lady-laders for each element, even if they suck. That leaves me with having to decide on who to get for Tech and Dark. Starcast and ... I dunno...Cortex...I guess? No one in Tech really appeals to me but Cortex does unlock a level I hear, so I'd go with him.

I'm probably doubling up on classes somewhere by doing this but I don't think they really unlock anything special either. Just Wow-Pows (or whatever they are called this year) for your create a figures, which isn't a big deal as I never use them anyway. I'm mostly trying to unlock the stages in the game, not so much trying to get all the parts and abilities.

Also Sensei Shrines. I heard you need them to get all Stars on a stage.

Get Mysticat for magic.
Chopscotch is pretty good for undead, after Pit Boss comes out supposedly December 2, we can better decide.

My team will end up being Ambush, Air Strike, Starcast, Mysticat, Chopscotch, Barbella, Aurora, Flarewolf, Tidepool, and Ro-Bow. One of each element and one of each class.

I'm planning on having all villains (besides Grave Clobber) so I can unlock everything with as few Senseis as possible.
