Cards through battles
Steam says every battle brings players closer to new unique cards and expands their arsenal. It also says rarities, talents, and hidden synergies create more combinations as players continue.
Build a collection gradually
The store description says a collection evolves over time and becomes more specialized, shaping a player’s style. Treat that as a broad progression description; Steam does not list card pools, drop rates, duplicate rules, or guaranteed unlock schedules.
What remains unknown
No exact rarity odds or card acquisition table is published in the cited store material. Check current in-game and developer information before relying on specific numbers.
