I'm with Ithry on this one.
A2 would be my preferred choice, because after looking up what the card does, there probably should be some villains in there somewhere. Coming from a decade of being a Vorthos, I think cards always read better when there's a synergy between their rules, title, art, and even flavor text; while cards in a set can build off one another, having elements of a card not line up with each other leads to the card feeling confused, or like it wasn't thought through. In that respect the A sketches are the best bet because they actually show what the card is supposed to do.
Between A1 and A2 is tricky. Honestly I would like to know what the plans for the rest of the set are. It's hard to say with this only being the second card art whether the typewriter being front and center would be too overused to go with A1. I equally like both ideas in the A sketches: the one that the typewriter was the weapon to defeat the villains and the one that the typewriter was a villain that was defeated. Of the two, I can't decide which is the better idea.
C2 is in third place just because of how silly it is. I'm not really convinced that it belongs on this specific Twilight, but it's a brilliant little portrayal of our beloved little shipping purple horse. I'd love to see this design used elsewhere, but again, I'm not really convinced that Element of Magic Twilight is the card to have it on.
