Interestingly, that was one of the original considerations for _Magic: The Gathering_ --- but somehow, my main (Commander) deck has become an unpocketable behemoth which is tedious to shuffle and which requires a box containing:

- play mat

- dice

- counters

- tokens

(and constant supervision since I had to add a rider to my insurance policy 'cause while my Elvish Archers are no longer in it, some rather valuable cards from when I first started playing are still in it)

There is also a geeklist for just dungeon-crawling games played with pen and paper:

And some "Roll and Write" games in general:

Onirim is good but the phone app is better since there’s so much shuffling. Cursed?! is one of my favorites. Galdors Grip is really cool in that you can play it in hand, you don’t need a table, so you can play it anywhere.

Pretty much love all the Simply Solo games from Button Shy Games.
