In recent years, most of deluxe villains items usually are released in P-Bandai....

Gifu's stamp more likely is similar to Another Ridewatches and Alter Ride Books because monstrous design.

Some of villain items are still released in regular releases. The examples is Evol Drver, Force Riser and Thoushandriver.

Also, be aware that the puns aren't always referencing the catchphrase. Sometimes, they reference the Transformation Jingle or they reference the song.

From the Kamen Rider Wiki, here are the phrases at the end of the auxiliary Vistamp Transformation Jingles and what they reference, with my own edits

• Eagle: Japanese Line: "Omae no hane o kazoeru!"; English Translation: "Count your wings!" (Based off of Kamen Rider Double's catchphrase "Now, count your sins!")
• Mammoth: Japanese Line: "Hanakkara Kuraimakkusu da ze!"; English Translation: "This has been a climax from the start!" (Based off of Momotaros's catchphrase "From start to finish, I'm at climax all the way!")
• Megalodon: Japanese Line: "Torisugari no Hu-Hu-Hu-Hunter!"; English Translation: "Just a passing through Hu-Hu-Hu-Hunter!" (Based off of Tsukasa Kadoya's catchphrase "I'm just a passing-through Kamen Rider." and Decadriver's shuttering sound effect used in Final Rides like "De-De-De-Decade!")
• Batta: Japanese Line: "Semaru hoppā! Henshin!"; English Translation: "Approaching hopper! Transform!" (Based off of the opening lines of Let's Go!! Rider Kick "Approaching Shocker, the infernal army." and Takeshi Hongo's iconic transformation call "Henshin/Transform!")
• Ptera: "Flying by! Complete!" (Based off of the SB-555B Faiz Driver's transformation announcements "Standing by!" and "Complete!")

So, Double Eagle Vistamp simply references their catchphrase, Den-O Mammoth Vistamp references Momotaros's Catchphrase, Decade Megalodon Vistamp references both Tsukasa's Catchphrase of just being a passing-through Kamen Rider and references the Decadriver's Final Ride stuttering, the 1 Batta Vistamp references both the opening lines of the main theme of the original Kamen Rider Series and the famous "Henshin" announcement, and the Faiz Ptera Vistamp references the SB-555B Faiz Driver's Transformation announcements. So, therefore, they will likely reference more than just the catchphrases with these puns.

Like the Gaim Kamakiri Vistamp might reference the Transformation Announcement of the Orange Lockseed, "Hanamichi on stage!" replacing "Hanamichi" with "Kamariri".

Addendum amd correction. Hana in this case means nose.

Sickle (something) on Stage!

I don't exactly know Japanese, I was depending on the Kamen Rider Wiki.

I guess.
Though, how would they change something, possibly the catchphrase or song of Kuuga, to make it Lion-related?
The Ending of each auxiliary Vistamp's Transformation announcement doesn't seem to be very consistant. So, the Kuuga Reference has to somehow be Lion-themed, the Ex-Aid reference has to somehow be Jackal Themed, the Fourze Reference has to somehow be Gorilla (Kong) Themed, and the Zi-O Reference has to be Brachiosaurus-themed.
I think that the Wizard-based Vistamp will reference the Wizardriver saying "please", the Kabuto-based Vistamp will reference "Cast Off", and the Build-based Vistamp might reference "Best Match".

'A Brave New Legend'?

I guess, as well. But I was looking at this video featuring the Mammoth Vistamp

and saw in the comments this from secretasianman108.
Which is surprisingly true! With the Mammoth Vistamp, the "Screen" turns red. With both the Eagle Vistamp and the Batta Vistamp, the "Screen" turns green. How does it do this?

There seems to be a display underneath the part of the screen that has magnetic fillings.

The driver "reads" the Vistamps through chips in the back of the Stamps, but the only information it gets is the color. Sounds are completely in the Vistamps, and the shapes are through the previously mentioned magnetic fillings.

I am speaking about the color of the lights that get shown after you pull the lever when Transforming.

However, I am looking at the Revice Vistamp Page on the Kamen Rider Website (https://toy.bandai.co.jp/series/ride...ecial/vistamp/), and have seen some images with text that I want translated. They are about the Vistamps whose forms haven't been revealed yet.
