Reactor Realms does not require a purchase to start playing. The physical catalog is temporarily paused while Preview v1.5 receives new art, rules work, and product updates. The free First Clash web Print & Play remains available while that work continues.
The free Thornbound and Gloomborn Print & Play sets are complete playable Common-card setups, not a half-match demo. Printed products are for players who want professional cards, higher rarities, collecting, more deckbuilding choices, boosters, and accessories.
Two complete faction decks in one professionally printed starting experience. You can still play both sides free first.
First Clash combines the Thornbound and Gloomborn Clash Decks into an 84-card physical starting product: two complete 42-card faction decks. Each deck includes 2 Guardian Dragons; during setup those Dragons are set aside and the other 40 cards become that player's Silverpool.
Each deck is complete on its own and can be expanded later.
A complete 42-card faction deck. Two of the 42 cards are Guardian Dragons; during setup they are set aside and the remaining 40 cards form the Silverpool. Settlements are part of the Silverpool.

Reactor Realms is new, and useful feedback matters. If you notice confusing wording, balance concerns, print issues, packaging problems, website problems, or simply have an idea that would improve the experience, send it in.
