Also we don't technically know the effects of the time travel. it's like going back and killing hitler, you could end up making everything worse. Like if Tendou got rid of W's driver then accel would be the only standing rider against The Museum and potentially screwing over Fuuto and possibly za warudo.I feel like that is a good counter for thinking that time travel beats everyone because you could screw everything up. and if he tries to do something like Mai tried to he could just end up locked in a never ending time travel fiasco trying to stop his past self. Aside from that for me it's hard to say but I would say either kiwami or tridoron because you have all the previous powers in one.
