Ghoulcaller's Chant

The modal split here is the whole design: pay one black mana for general recursion of a single creature, or skew the same spell toward Zombie tribal and pull two bodies back at once. That second mode is the reason the card exists, a recursion engine priced for a deck built on attrition, where filling the graveyard is part of the plan rather than an accident. Single-creature return is the floor; the Zombie clause is the ceiling, and the gap between them is the spell rewarding you for committing to the tribe. Black has always had recursion at this price (Raise Dead is the baseline this descends from), but the modal upgrade is the wrinkle: a card that stays useful with no Zombies at all and becomes a two-for-one in a deck full of them. It demands nothing from the cards already in front of you and everything from your graveyard, which is the right ask for an aggro-attrition shell that expects to trade bodies early and rebuild from the yard.
