You hold four cards from an eight-card loadout. Mana trickles back every second.

Aim and throw a card mid-fight. It lands as a fireball, a wall of stone, a trap, a totem, a Bone Knight or a Phoenix. Your opponent is throwing cards back.

Blow the Last Horn and you become a bear. Slash, charge on all fours and call lightning down on your opponent.

Last Horn is a Mythic card. There are others. Pull one and find out.

Six schools of magic: fire, frost, storm, shadow, arcane and holy. Every win earns a pack.

Duplicates level a card from 1 to 7. Its border takes its rarity, then holofoil, then a full-art scene. At level 7 the art moves.

Pull a Mythic and an eye opens on the card back. Trade cards with other players.

Every arena turns on you in its final minute.

Meteors rain on the Infernal pit. The ice breaks under Frostmere. Skyreach crumbles into the clouds. Tidal waves roll through the Drowned shrine, and poison spores drift through Witchwood.

The crowd goes wild for a big hit.
