Overall this is a unique game for this unit, while the general idea of casino games in a videogame/app is fairly common (which you point out at one point).
In terms of a novel idea, I would have loved to see you lean more into the wario ware inspiration, maybe by making this be a quick-fire play through different card games, but instead of playing a full round, players need to complete the next move (getting points for quality of move, winning, or not losing etc). Despite this, if you can get this game working, it is ripe for a good assignment 3 grade.
There'll be some technical gotchas along the way possibly, and things to think about, like the fact you can't just pick random from all card types (random with replacement), but rather ensure that cards don't appear again etc (random with replacement). There might be some more difficulties with implementing the rules, and with making things effectively turn-based, but it should be a straightforward challenge, goforit!!
