I'll add some off-the-wall suggestions for deck/hand/pool-building:
A Study in Emerald: This is a rather weird, "everything but the kitchen sink" type of game, set in a mash-up universe of Sherlock Holmes and Cthulhu stuff. The main driver of the game is deck-building, but certain cards you get add agents to the board that you then move around - and they might fight other players' agents, blow up some eldritch monsters (who have become royalty in this world), or help you hold down cities on the map. Did I mention there are hidden roles in the game?
Lewis & Clark[:/B] This is a hand-building race game (different from a deck-builder, in that you don't get that many cards, and you don't shuffle). There are a lot of careful management of resources and timing your advances just right. This game will burn your brain with how much thought you have to put into your planning.
Food Chain Magnate: This is another hand-building game, essentially, but with a lot of important stuff happening on the board. This game is expensive, and it's hard to recommend because of that - but it's also such a nicely balanced mix of managing your resources, interaction with other players, beating your opponents to the punch, and that tense turn-by-turn progression.
