Archive can increase your handsize, but the trashing is slow, and the decks are very bad until you get the Familiar curses cleaned up and some of your Coppers thinned, so the cards it is getting you aren't all that good until the late game. I think I only had one. Maybe should have had more, but Royal Carriage just seems better. I recall taking something over one of the last Carriages in this game, and immediately regretting it because I realized my opponent would get it instead.
Engineer for Apprentice food seems completely not worthwhile. By the time you play the Engineer, and trash a Silver to Apprentice, you haven't even increased your hand size. Also your Village is only Royal Carriage, so terminal space is valuable. You could gain Potions instead of Silver and it would increase hand size by 1, but it still seems like too much work for too little gain.
