The best Retro-Rulings Discord Bot!

RoboMika is a discord bot built for Retro Format Rulings.
It's specifically designed for Goat, Edison, and HAT,
but can be helpful for any other retro format.

The bot also provides an updated version of PSCT for cards, even those which did not have PSCT at the time. For example, searching for "Megarock Dragon" shows the PSCT Nomi indicator ("Must") which does not appear on any of its printings.

Card missing in the Database? Let me know!

Useful Unicode (this isn't required in your submission, but you can copy it if you like): Ⓤ Ⓒ Ⓢ ① ② ③ ④ ⑤ ●

Thanks for helping! Your ruling will be added after a review period (this could take up to a week)

13th Sept 2022:

  • Removed mmt command (use mme instead).

17th June 2022:

  • Added all UDE Edison rulings (a few thousand more cards).
    These don't have PSCT, and are quite wordy (much like the goat ones).

15th June 2022:

  • Added all Goat cards which don't have rulings.

8th June 2022:

  • Added Goat Format Rulings.
    These are from, and as a result, appear quite differently to the other (Edison/Tengu/HAT) rulings.
    They are not linked to Card Pages, and are formatted quite poorly. 

  • I may work on the formatting for Goat in the future, but this feature will not be coming anytime soon.

5th June 2022:

  • Bot released.
