I'm surprised no one mentioned the Cartomancer archetype. I played one and it was great, I got all the necessary feats by level 7 by dipping here and there, was able to deliver ranged touch spells, and got Arcane Strike for free.
Strong Arm, Supple Wrist was a great trait I took to avoid a level in Hurler Barbarian, and I enchanted my Harrow deck with the Distance enchantment, so it was a 30 ft toss not counting feats. that's a good deal since as a Witch you had to be within 30 ft of nearly everything anyway with your hexes. Since Harrowing is banned in PFS anyway i didn't have to worry about my cards being destroyed (which I didn't do anyway) and they get the Returning bonus for free. It's worth a look.
