But why would he try? Seriously;
-He loses; Shiggy and the LoV martyrise him. Now OfA is down and when he walks out of prison to the point he even named the guy years in advance who would bust him out after a Greek event related to the prisons nickname
he has no direct competion and much more powerful, independant goons.
-He ties; See above, now with the aid of OfA being ded and society even more impacted
-OfA runs; free win, society is fucked
-He wins; He wins.
There was no forseeable scenario where AfO did not come out of that the overall victor. He only needed to add a few quirks to make it look like he was trying, hence why almost all of them were cosmetic at best and hence why he had a leisurely chat with OfA beforehand-unlike with Nana of which he killed almost on sight with AoE quirks that OfA cannot easily deal with.
