Made this a little while back, and completely forgot to post it here. It's quite a wall of text (~5300 words), but it's well worth the read, and details almost everything important when it comes to building a good combat deck in Absolver. If you're new or don't want to read that many words, the "fundamental concepts" section contains the most important things to understand when making a deck, though the other information is just a relevant.
