Shadow Clone itself is a literal cheat. It makes every jutsu OP. For example, Flying Raijin x Shadow Clones, you can teleport to any shadow clone, anywhere at any time and they can do the same - ofc the limiter is chakra amount for sustainability. Since none of the MC's moves use chakra, because they aren't from the Nin world- if he learned Shadow Clone instead of Flying Raijin, he'd be unstoppable- he could instead put all his chakra into shadow clones and then they could swarm the enemy instead. So now he'd have quantity AND quality.
