The solo play deck is very easy to use as an add-on; not finicky at all. I'm not a fan of solo play at all, though, so that's a bonus -- the real gem of this set is the inclusion of *every* promo card for Core Worlds -- all of them. Honestly, I had nearly all of them already and *still* bought this package, because "nearly" meant I hadn't ever gotten the otherwise almost impossible to find promo set of Pre-Game draft cards -- there are 10 and all are top-notch, but almost lost to time because they and Champion of Ra (a 1-card promo) were rewards for a poorly advertised and frankly stupid Kickstarter attempt to make a Core Worlds digital game, and the very dumb decision was made to make physical cards a totally exclusive promo for this *digital* item -- duh. Thus, this is basically the only way to get those cards, and you get every other promo, too. A great problem solver -- plus a nice AI deck for solo play -- for an overlooked but excellent, immersive deckbuilder.
