Bloodline Bidding

Mass reanimation has always priced itself by the funeral, not the exhumation: a bulk return-from-graveyard effect asks you to fill the yard and then pay dearly to empty it back onto the battlefield. What convoke does to that math is the whole trick. The sticker price of eight is a fiction the moment you have a board, because the same creatures you are about to rebuild can pay for the spell that rebuilds their fallen kin. Tap a handful of survivors, name the tribe, and the graveyard empties for a fraction of the stated cost. That coupling is the design's real content: it wants a wide, one-dimensional board, precisely the kind of deck that has already lost half its creatures to a sweeper. The narrower your creature-type spread, the bigger the return, so it rewards commitment to a single line rather than a toolbox. There is no exile clause, no life payment, no downside counter keeping it honest; the balancing lever is entirely the graveyard restriction (they have to be in the yard) and the sorcery-speed window, which means the wrath you are recovering from resolved on someone else's turn and you are answering it a turn late. The tension it resolves is the old one of overcommitting into removal: it turns the graveyard into a reserve army and hands the reload to the very creatures that will crew it.
