What about Mizore Shirayuki? There should be a Mizore card since she is also voiced by Rie Kugimiya.

Imagine if Iwaki Rizel (as Yuuki) has a K-Touch (K for Kugimiya), then the transformation will go like this:
Shana, Sanzenin Nagi, Aisaka Taiga, Astarotte, Alisa Bannings, Kagura, Louise the Zero, Nena Trinity, Shirayuki Mizore. Final Kugyuu Ride: Kataoka Yuuki!
And Iwaki Rizel becomes Kataoka Yuuki Complete Form.

Shana
Sanzenin Nagi
Aisaka Taiga
Astarotte
Alisa Bannings
Kagura
Louise the Zero
Nena Trinity
Shirayuki Mizore
Final Kugyuu Ride: Kataoka Yuuki

*moments later*
Attack Ride: KUGIMIYA RIE!

Final Attack Ride: KATAOKA YU-YU-YU-YUUKI!

Taco Powered Drill Break!!!!!

Attack Ride: Four Tsundere Wonders!

Add Hasuta to the mix and Rizel's character set will be complete. Hasuta is voiced by Rie Kugimiya in the TV series Haiyore! Nyaruko-san.
