Mtenda Griffin
Tribal recursion built one effect at a time, from a moment when caring about a creature type meant stapling a modest, conditional payoff to a single body rather than wiring a graveyard engine into the deck. The activation cost reads as trivial (white and a tap), but the effect does two things at once: it bounces this creature back to your hand and returns a Griffin card from your graveyard to your hand alongside it. That self-bounce is the friction. Every time you fire the loop you leave the board and re-pay four mana to redeploy the body, so the engine grinds rather than chains. The other load-bearing constraint is the timing window: the ability works only during your own upkeep, which means you cannot hold it up at instant speed to dodge removal, cannot fire it on a teammate's turn, and cannot rebuy a blocker mid-combat. The target lives in the graveyard, so the loop pulls back any Griffin you have lost (including a second copy of Mtenda Griffin), but only by sacrificing this one's presence to do it. What survives all that gating is a slow, circular source of Griffin recursion, throttled steeply enough on tempo and timing that it never threatened to do more than accumulate value over many turns. A clean artifact of early tribal design, where the reward for committing to a creature type was deliberately small and always one body at a time.
