Early Game
Turns 1-2
Make efficient plays with Defile and Omen of the Dead and set up your mid-game. Don't overextend into sweepers if you have a lead.
Mid Game
Turns 3-4
Develop your board while leaving up interaction. This is where the deck's threat-answer flexibility shines — read the matchup and pivot accordingly.
Late Game
Turn 5+
Leverage Marshmist Titan and Blight-Breath Catoblepas to dominate the late game. Resolve your biggest threats and protect them.
