Teneb, the Harvester

The interesting move here is where the recursion reaches: this Dragon pulls a creature card from any graveyard, including the opponent's, onto the battlefield under your control. That redirection is the whole strategic axis. A freshly killed bomb across the table becomes your problem solved and their problem doubled, and the cost is folded into combat rather than paid up front. Connecting with a 6/6 flyer is the trigger; the is the toll on top. Where most Abzan reanimation spells ask you to stock a graveyard before you cast them, this one is a self-replenishing loop: it swings, it mines whatever the table has buried, then it swings again to mine the next thing. The body is built to make that loop reliable. Flying clears most ground blockers and pushes damage through to the player, which matters because the ability only triggers on combat damage to a player: a blocked, traded Teneb does nothing. Six toughness survives most of the burn in its color spread, and six power threatens lethal fast enough that the engine compounds over a long game rather than asking for setup. It belongs to a horizontal cycle of wedge Dragons that each re-expressed a different identity across an alternate-timeline framing, but Teneb is the one whose ability rewards grinding by design: the slower the table and the deeper the graveyards, the more each connection extracts. The kill condition and the value engine share a single point of contact.
