Artifact

Artifact is a digital card game set in the Dota 2 universe. Matches play out across three parallel lanes simultaneously—you deploy units, cast spells, and destroy enemy towers in each one. There's no mana cap, no hand size limit, and no restriction on how many units you field, so games escalate into large-scale board states. Every action your opponent takes triggers a chance for you to respond, creating back-and-forth exchanges rather than taking full turns in isolation. The game went free-to-play in its Classic version, unlocking the entire card pool from the start. If you bought the original paid release, your collection converted to cosmetic Collector's Edition versions.
