i genuinly think quite the oppposite because we haven't really seen that meny useless combos. like with the exception of Shushu and Mira every other one has been really usefull even ones you wouldn't expect. also i don't really see a way that you can make his transformation be that op just because tenkas ability by itself is already very op. also more so of the transformations i'm really looking at how a combo could work as well. like more then 1 rider type stuff hell one of the best combos would have been bell and yakumo ezo( the tornado girl) for an invisible high speed destruction but well....Triple swimsuit reward? Top tier.
It's going to be stupidly OP, there's no way after so much anticipation he'll throw us a useless one like Shushu's.
