btw, is Black and RX rider the original guy from wayyyyyy back then? i suspect so because they are so old. no reason to get old guy if its not the same person right? 
havent watch wizard yet. not planning to do so till the whole series is complete (i hate cliffhanger )

35 Years Old High School Student

he is "leader" of the so called "rank a" group student (who can freely bully rank C & D's students, freely use activity room as their lepak/poteng base etc etc)

Now Wiseman looks strong, even Infinity also can't even touch him.

Kuuga.
Agito is more to psychic/godly power

Godai got the power first before Souichi -- If you are talking about Souichi's sister's power, yes, she preceeded Godai's Kuuga arcle power possession.
But Agito's power exist long before Kuuga's as it is originated from god's power. lol

Agito power is just pieces of the said god's power, so cannot really say that Agito > Kuuga.
Kuuga Rising form rider kick pawns all heisei era rider kicks.
Bom Atom yo.

Wizard earlier episodes (before the death of Pheonix) were at decent level though, and they have better pacing. Until the point were Nitou starting to act like a joker, the pacing of the story became unbalance and too much unnecessary jokes were forced into the plot.
It was still okay though, Infinity debut episode and Sora psychopath episodes were okay and improve the broken pacing back.
But (spoiler, in case you have yet to watch these episodes)

i'm just hoping pheonix coming back from the sun....

IMO, the production team should not take that kind of action and force it into the story. Let the dead be dead. Reviving the Phoenix plot have been used twice and it will bring forth again unnecessary plot (thus ruin the story essence) if they revive him once again.

I am still wondering... is there any meaning behind RX acronym?
