Artifact was Richard Garfield's vision brought to life through Valve's craft - a card game that respected its players' intelligence. Three lanes, five heroes, infinite decisions. It asked you to think three moves ahead while the world wanted you to tap and swipe.

It was too complex, they said. Too expensive. Too ambitious. Perhaps. But for those who played it - who felt the weight of choosing which lane to abandon, who agonized over initiative - it was something rare.

The servers still run, empty. The cards remember, even if the players have moved on.
