Clash of Decks: Treachery

About this board game

Clash of Decks: Treachery is a 2022 standalone expansion for 1–2 players, with games lasting about 8 minutes. Create your own deck with 8 creature or incantation cards, then face rival Lord-Sorcerers in a battle to destroy their Stronghold.

This 36-card expansion introduces two special abilities that add distinctive effects to card positioning and hand management. Vanish activates after its owner suffers at least 1 Damage without being destroyed, moving that card to the furthest position away from the Bridge on its line.

Vanish has specific timing rules when combat is involved. If the owner was attacked by a Creature, the ability triggers after the attacking Creature has finished and resolved each of its attacks. It also triggers before the Instinct Special Ability.

• Vanish: Move the damaged, surviving owner to the furthest position away from the Bridge on its line.
• Mercenary: When the owner should return to its owner’s hand, place it in the rightmost position in the enemy’s hand instead.
• Solo play: A Mercenary card returns on top of the AI’s deck pile instead.

Mercenary is a malus: the card goes to the opponent rather than returning normally to its owner’s hand. To compensate, a Mercenary owner is inherently more powerful than other cards with the same mana cost.

With quick 8-minute play time, a compact deck-building format, and clear new rules for damage, positioning, and card returns, Clash of Decks: Treachery gives Lord-Sorcerers another way to shape their deck before challenging an enemy Stronghold.
