Game Plan
Early Game
Turns 1-2
Prioritize hitting land drops and hold up interaction. Answer the most threatening plays rather than developing proactively.
Mid Game
Turns 3-4
Start transitioning from pure reaction to building card advantage. Identify your path to a win condition while keeping answers open.
Late Game
Turn 5+
Deploy Champion of Stray Souls and Eliminate the Competition when the opponent's resources are exhausted. Keep interaction mana open even when winning — never tap out unnecessarily.
