I would like an app that actually emulates a deck of cards.
Imagine you are sitting with freinds end family and want to play a gard game, but don't have any cards laying oround.
The app should be able to create card games based on the rules and mechanics of the particular card game.
The ability to choose how many players
Decide how many cards each player should hold
What is allowed to put down depending what's on the table and so on.
It should include multiplayer and ads.
