For me, ten shadows is already OP and versatile, And Yuka lead me to this thing.

Yuka instead of summoning the shikigamis uses their abilities just like Sukuna did with max elephant, so... This methods would probably be better in terms of CE waste 

Divine dogs: just like Yuka, using the clawns of the divine dogs 

Nue: using nue's wings on you so you can fly much faster and attack at the same time you have both hands free (something like wing king), or punching with nue's electricity as well, being some kind of kashimo with the tickle thing 

Orochi: partially summoning orochi, using him as an extension of your arms to catch and bite the enemies even from under the ground 

Frog: using the tongues coming out of your arms as a web, so you be kinda like spiderman there 

Bunnies: probably just summoning them, is what they are there for tbh

Max elephant: Blastoise goes brr, shooting water like a mf not really using that much CE and make something like the blood waves choso did, also high pressure water like Sukuna, maybe adding your overhead attacks extra mass by partially summoning the feets 

Bull: moving faster in a straight line then combine with a max elephant fist, maybe also imbuing bull into jabs so your jabs stacks more momentum and strength 

Deer: free RCT output, imagine like the horns growing on your back and then RCTing yourself or anyone, even one tapping CS 

Tiger funeral: we've never seen him or what he does, there's no mention of his either apart of it being a white tiger so probably something with cold(? Pure speculation 

Mahoraga: summoning him and the wheel is already OP, but imagine that the one who adapts is you, so instead of summoning Maho you are the one adapting at the cost of lots of CE 

Merges: I'd honestly keep the concept of them as they are, but you can't use the abilities of the shikigamis involved into the merge 


Shadow hiding: same shit 

Shadow control: imagine something like Shikamaru from Naruto, if i step over your shadow you'll feel my feet too 



CTs that could be stronger bia other understanding?
