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 Shattered Seraph and Snow Day when the opponent's resources are exhausted. Keep interaction mana open even when winning — never tap out unnecessarily.

The Play Style hexagon uses the same data to place the deck on the aggro–control–combo–midrange spectrum.
