This is way more likely to kill something than Deadeye Harpooner, so common is not appropriate.
As for crackdown generally, the flavor is solid and I like that it is mechanically simple, but you do want to be careful about having too much of a mechanic that discourages attacking even when no cards with that mechanic are on board.
I like this card, though I wonder if it might do stupid things with Stinkweed Imp.
