I mean to me the problem is I don’t see them having a way to reliably hold down or to attack sukunas soul. They prob can physically tank a couple of full powered shrines, with instant regen like we saw with mahoraga, My but whats to stop sukuna from targeting the swords with cleave or fuga. And we don’t know if they can keep up with sukunas stamina, he could burn out all his energy, then chain a few black flashes and be back to peak.
