Choose your S-Timer

Every deck is led by an S-Timer, a hero whose affinity shapes the cards it can command. Three affinities, three ways to play — and leaders who walk between two of them.

Ashara, Firedancer — Dark S-Timer card

Ashara, Firedancer. Burn, poison and sacrifice: power that always comes at a price.

Ursan, Bearlord — Wild S-Timer card

Wild

Ursan, Bearlord. Beasts, roots and Wonders of the living world, growing stronger together.

Nebulina — Tech S-Timer card

Tech

Nebulina. Constructs, relics and clever machinery for players who like to plan ahead.

S-Timers Chronos

Face the Exarchs

Solo battles against Exarch decks that play by their own rules, from a gentle start to a real challenge.

Challenge a friend

Online games against your contacts, quick or best of three, with a server that keeps every move fair.
