Serpent's Pass - Magic: The Gathering | Avatar: The Last Airbender (Common) [TLA-279]

Serpent's Pass enters the battlefield tapped, providing either blue or black mana when tapped. Its ability to sacrifice for card draw can help you filter through your deck in the late game, making it a useful tool for control or midrange strategies that aim to maintain resources. However, its initial tap means you won't have immediate access to mana, which can be a drawback in fast-paced games.
