Thalia's Geistcaller
Two graveyard-value archetypes rarely share a home, and this Cleric is built to bridge them. The flashback-and-recursion crowd wants to cast spells out of the yard; the Spirit tribal and go-wide crowd wants bodies on the board. Here the reward for the former feeds the latter: every graveyard cast spins off a flying token, turning a recursion engine into a token engine without asking you to change your spell mix. The sacrifice ability gives those tokens a second job. They are not just chip damage and blockers; they are ammunition, each one a one-shot indestructible shield that lets the 3/1 body block above its weight or crash through a stalled board. That fragile 3/1 with lifelink is the tell for how the card wants to be played: aggressive enough to want the swings in, delicate enough that it needs the Spirits to survive the crackback. The token trigger and the sacrifice ability chain in one direction: casting from the graveyard stockpiles Spirits, and those Spirits buy the attacker the durability to keep swinging. Strip the graveyard of recastable spells and the card sits inert, a body with no fuel, which is what keeps it a support piece rather than a self-sufficient threat. What it represents is a rare pointer toward a recursion identity white usually only touches through creatures rather than spells, with the spellcasting itself as the trigger.
