Oooh, baby, yes!!
Pocket decks are great; so easy to carry around, and with a hard case that would be perfect!
Actually, I have both the standard and pocket versions of the Hanson-Roberts, and for the record the standard is about playing-card size, smaller than most other decks. The pocket is smaller, but nowhere near as small as a mini (I have 2 different decks in mini).
The M-G is full of closeups, which would translate very well into a pocket size. If I have no trouble with the H-R, I wouldn't have any with the M-G!
(Now if only they'd come out with a pocket Whimsical, or at least playing-card size like the H-R, for the use of children...)
