AstraSet.pro is an unofficial, free, ad-free fan database for Echoes of Astra, a trading card game. It helps players explore the game’s cards and sets, find rules text and different printings, and organize their collections. The searchable catalogue includes cards across the game’s five affinities—Lux, Nox, Solara, Caelum, and Terra—as well as neutral cards. Players can browse sets, including the 160-card Imperion release, and view available products such as booster boxes, starter decks, and display bundles.

The site also supports deck building: users can search the catalogue, add cards to deck zones, and check deck legality as they go. Its stated deck guidelines include a minimum of 50 cards, a maximum of three copies per card name, and no more than two affinities. Additional resources include game explanations, a card-symbol legend, news, lore, and blog articles about deck affinities and product releases.
