Fixed, I kind of agree with your line up. That's kinda how my SHF are being displayed right now since I only collect first and final form riders.

I just don't like the card faces. DiEnd's Final Form should've played up him being a theif, somehow. Turned the DiEnd Driver into a Rifle, given him a long coat. A smaller helmet. Something.

Between the two, I prefer Diend's, mainly due the fact that the card gives him a set of visible eyes rather than the giant radiator visor.
They're both ugly as sin, but Diend's is better.

They could've done a Cosmic States kind of thing instead. Use the same K-Touch they have already. But when he touches whatever Rider he wants he takes on their Final Form. And when he changes back, an aspect of that final form retains on Decade somehow.

I used to dislike the two, but both have grown on me since. I just wish Diend's had seen a bit more action.

What would be Kamen Rider Double's Cyclone Accel Xtreme form be then? I know they don't make it in the show or movie but its supposedly stronger then regular Xtreme.

Honestly don't know. It all depends on what you consider a Final Form. If you count movies than Accel Extreme, if you don't then Xtreme. I never saw either so... I don't know :lol

In the context of the show Cyclone Accel Extreme is supposed to be his ultimate, final, and most powerful form. Shroud created the driver and memories which resulted in Skull, W, and Accel. And she is the one who explicitly says that CAX would be the ultimate form. That Phillip would have to ditch Shotaro to use it. But really that's just Shroud's predictions and intentions. But then again she designed the system, she would know right?

Since it wasn't really ever seen in show and only appeared in a few games it's hard to say. The only confirmed things about it are what she said. The games (Climax Heroes) show that this form can use the Prism Bicker and Engine Blade simultaneously as well. We won't ever know how powerful it would have been but I imagine right on par with CJX.

I'm sure if that thing ever appeared in the show it wouldn't have worked because of friendship or love or brain patterns or some BS like that.

It's nothing. It doesn't actually exist in the show as anything other than an idea and doesn't count as any kind of form in my book.
