how about
The Broken God? it's biological manipulation isn't exactly applicable in this since everyone here is inorganic
It's absorption requires the broken god to shove whatever it wants into it's chest cavity, and with stats equalized that can be seen as a difficult task for it to do.
SCP-882, with stats equalized, becomes useless as they could unstick themselves due to equal LS, and it's psychosis requires it's opponent to have a mind, which comes to a problem when over half the contestants don't have a mind it can effect.
