1v1 Duel
The standard, competitive execution of OSMCG, balancing economic efficiency against brutal tactical assassinations.
2.1 Match Setup
- Board: 24"x24" (~60x60cm).
- Deployment: Each player claims a 6" deep deployment zone along their respective board edge.
- Objectives: Place 5 fixed Objective points symmetrically across the board (1 dead-center, 4 flanking the quadrants).
2.2 Victory Condition
The first player to successfully secure 10 Victory Points (VP) immediately wins the game.
2.3 1v1 Hero Penalty
When a Hero is successfully destroyed:
- The opponent immediately scores 3 VP.
- The controlling player must immediately Discard 1 card from their hand.
- The destroyed Hero's Mana pool is flushed and permanently reset to its original Starting Mana parameter.
- The Hero will Respawn directly inside their player's deployment zone precisely at the start of that player's next upcoming Upkeep Phase with full HP.
2.4 The Mission System
Victory Points are accumulated via a shared, globally visible 10-card Mission Deck.
- At the start of the game, exactly 3 Missions are revealed face-up.
- Both players compete to actively fulfill any of the 3 active Missions. Formally achieving the requirement first immediately awards the printed VP.
- The instant a Mission is fulfilled and scored, discard it and reveal a fresh replacement Mission.
