The cardcaster staff magus

So, these two archetypes stack and seem to make for a pretty sweet character concept (because who doesn't love gambit?). You even get the benefit of being able to spell strike with ranged spells, too, though you're forced to give up your melee spell strike to do so.

Does anyone have any experiences playing a combination of these archetypes? How did it go for you? Anything I should know about or avoid before giving it a try for myself?
