Sewers of Estark forces a creature to block alone this combat — a surgical combat trick that turns a single attacker into an unstoppable kill shot or saves a blocker from a gang-block. The cost is real: one black mana plus discarding a card, which means you're trading card advantage for a guaranteed result.

In Commander, Sewers of Estark is a niche combat trick that earns its slot in decks built around a single must-connect attacker — it answers the "but they have a blocker" problem at instant speed for one mana, which is the right rate. In Legacy and Vintage, it's legal but functionally invisible; those formats end games through stack interactions and fast mana, not combat math, so a discard-to-force-a-block reads as deeply underpowered. Oathbreaker mirrors the Commander logic at a compressed game length — if your planeswalker win condition requires connecting with a creature, Sewers of Estark can punch it through once.
