Why Play Fog

Perfect for stalling aggressive strategies and buying crucial turns when you're behind on board. Most effective against creature-heavy decks that rely on combat damage to close out games, particularly when facing lethal attacks. The single green mana cost makes it easy to hold up while developing your board, and it can completely blow out combat math when opponents overcommit to alpha strikes.

Format Notes

Sees its strongest play in Pauper, where the low power level and prevalence of creature-based strategies make the effect more impactful. In Pioneer and Modern, primarily appears in turbo-fog control decks that aim to prevent damage while assembling win conditions. Commander players occasionally include it in defensive builds, though spot removal and board wipes are generally preferred in multiplayer games.

Combos & Synergies

Forms the backbone of turbo-fog strategies alongside Teferi's Protection and other damage prevention effects to create multiple layers of protection. Pairs excellently with Isochron Scepter to repeatedly prevent combat damage each turn, effectively locking aggressive decks out of the game. Works well with board wipe effects like Wrath of God, allowing you to survive one more turn cycle before clearing the battlefield completely.
