Serpent of the Pass (TLA)

Creature — Serpent

If there are three or more Lesson cards in your graveyard, you may cast this spell as though it had flash. This spell costs {1} less to cast for each noncreature, nonland card in your graveyard.

Niche tempo creature for Lessons-focused blue decks. Serpent of the Pass rewards graveyard setup with cost reduction and conditional flash, but the payoff is narrow—it requires both Lesson synergy and a full graveyard to justify its seven-mana baseline. Outside dedicated Lessons strategies, it's outclassed by more efficient threats and better flash creatures at similar costs.
