[TF RyuShin]

I don't think Toei will use a fusion-oriented Kamen Rider. Orb already used it and it would be a bit wrong move to use it. Though, I don't know if they will use it for the 20th Heisei Kamen Rider. Anyway, if you ask me about the fusions for Riders, maybe it will go like this:
-Kuuga and Agito: Since, they are connected a bit and duh
-Ryuki and Blade: Cards users
-Kabuto and Faiz/Drive: Speed-oriented Riders
-Ghost and Wizard: Mystic-type Riders
-OOO and Gaim?: Don't know? Just came up in my mind
-W and Fourze: Tech-type Riders and since they have some similar elements
-Decade and Faiz?: Maybe a jerka** protagonist
-Hibiki? and Kiva?: Don't know? One of the remaining here
I don't know Den-O will fit whom, but maybe I will take a look at it. Anyway, for the questions, it might be too mainstream, but seeing Ghost fell over the top, how do you think you could fix it or any other mediocre series?
