Martyr's Cause turns any expendable creature into a free Fog for a single damage source — one mana to deploy, zero mana to activate, and it taxes your opponents' best attacks indefinitely. In sacrifice-happy shells like Atla Palani, Nest Tender, where creatures like Forsaken Miner want to die anyway, every activation is pure upside.

Atla Palani, Nest Tender
Atla Palani, Nest Tender needs her Egg tokens to die on demand, and Martyr's Cause converts that sacrifice into a damage-prevention shield — blocking a commander swing or a lethal combat step while the deck does exactly what it was already doing.

Martyr's Cause is a Commander card through and through — the effect compounds over a long game, and multiplayer tables give you enough threatening attackers to make the drain meaningful. In Legacy and Vintage it's technically legal but wildly outclassed; those formats kill you before a one-mana enchantment that prevents damage one instance at a time does anything relevant. Commander is where Martyr's Cause earns its slot: 40 life and multiple opponents mean you'll activate it several times per game, and the political angle of choosing which attack to block keeps the enchantment relevant even as the board evolves.

Current price
$1.00 cheap tier
At $1.00, Martyr's Cause sits firmly in the budget-staple tier — cheap enough to throw into any white sacrifice deck without deliberation. Supply is thin enough that the price is unlikely to crater, but don't expect it to climb unless a high-profile deck puts it back in the spotlight.
