Harvest is one I was waiting for. I never play it, and I believe it is as useless as it sounds. Early in the game, you can't use it as a slingshot to get up to 6 or 9, because your deck is mostly Estates and Coppers, Later, you're better off just getting Gold and Platinum instead of dicking around with this risky terminal. It cycles your deck, I guess, which is sort of nice? Maybe you could use this in combination with like Navigator or something to rearrange your deck but then you need +actions and this has already gotten far too complicated really. Harvest sucks.
