Serpent's Pass (TLA)

Land

This land enters tapped. {T}: Add {U} or {B}. {4}, {T}, Sacrifice this land: Draw a card.

Niche mana source for blue-black decks with sacrifice synergies. Serpent's Pass provides dual-color fixing at the cost of entering tapped, but the card draw mode requires significant mana investment and a sacrifice outlet to justify inclusion over more efficient lands. Best in Commander decks already built around sacrifice themes or in limited formats where fixing is scarce.
