Something I've wanted to do for a while now since I discovered the game that is Loteria, which is basically Mexican Bingo, played out as 54 calling cards instead of 100 balls. These 54 cards are adorned with artwork that's a big part of Mexican culture, like the game itself.
(Google did an amazing multiplayer Loteria game that tells you all about it. It's loud! https://www.google.com/doodles/celebrating-loteria)
So why not put a Star vs. spin to it? (Designs here are WIP)

Some of the cards have been replaced (if you seen the list of the original 54 cards, you'll know why), but most of them are intact. At time of posting, 20 cards have been done up at the moment, with the others featuring characters I've not done before, such as Festivia, Toffee, Buff Frog, the Bard from that episode, and Ludo.

On top of which, a secondary set of cards may be designed to create a modern-type card game based on elements of Loteria where you play as Marco, Star, Tom, etc and work your way to defeat your friends in good fun. Consider it a sparring match!
But the idea is to make Loteria cards for now.
Let me know what you think in the comments, and check out the Google link to see how the game is played!
