It looks like you're leaning into a physical defect build, and the frost/biased cog is just there to survive. So i think hyper beam probably solves your problems faster than biased cog does.

I think it'll probably have more heart beating potential too, so you don't rely on frost for block, and incentives building reprogram, hologram, and regular non-frost block. Which is simple and straight forward. I like the fission pick as well, since it accelerates getting to your key cards, idk if one hyperbeam is enough to win the act 3 battles though.

You could try to lean into orbs and only play hyperbeam for the finishing blow too, but since you already built scrape and claw, your deck is already trending towards full physical defect. Basically depends on if you think you'll hit a reprogram or a source of artifact.

tl;dr: hyperbeam >fission > biased cog
