But you're not taking away the fact that there's 5 of them. The team dynamic and ability to fight cohesively is one of Sentai's biggest advantages (Where as fights involving 2 or more riders tend to come down to 'Rider A runs in and slashes, then slides away so Rider B can run in and slash too.').

On an individual by individual basis, yes, the Rider's arsenal and power set would probably beat out any individual Sentai member, but (For the most part), that one Sentai character has 5 others behind him, ready to help.

Also, KROOO (The user), you forgot to mention Ryuki's Strange Vent card, which transforms into other cards when he uses it.
