This is a class with little resource depth, based on doing one large attack and with little inherent toughness. The damage progression you would want to follow is the rogue.
I like the idea of using 1d12s as the damage dice (I think they're more random and a little more intimidating, which fits the feel of the class well). So I'd probably want to see 1d12+Int at 1st level, and then bump it by 1d12 every 4 levels after 1st (so 5th, 9th, 13th, 17th). That parallels the growth of rogue damage, although rogue is slightly ahead, which fits since the rogue has (slight) restrictions on the use of sneak attack and is usually melee.
Then, I like the idea of a two-pronged subclass like Warlock, with the element being one prong and something else as the other. I'd make some utility talents as the elemental contribution, like gaining a fly speed for air, or make walls of stone for earth.
