Octavia, Living Thesis — Tentacles of the Tome

Octavia, Living Thesis is a high-cost finisher built to reward a graveyard full of spells. Cast normally and you get an 8/8 Elemental Octopus with ward that deters cheap interaction. Pack your deck with instants and sorceries to shave eight colorless from its cost and turn a slow game into a sudden board reset. The card reads like a study in value; you trade tempo early for a reliable, repeatable threat that scales with spellcasting.

In play Octavia doubles as a deterrent and a utility piece. Ward eight buys time for your setup while Magecraft provides a predictable way to inflate another creature into an 8/8 for the turn whenever you cast or copy a spell. Use cantrips and cheap interaction to feed the graveyard and trigger Magecraft while you work toward the reduced casting cost. The card fits well in storm adjacent and control shells that aim to convert spell density into tangible board presence.
