Most graveyard recursion in black cares about creatures broadly, about a single named target, or about mana value; here the filter is the type line itself. Sacrificing the body returns every legendary creature card from your graveyard to hand at once, a narrow-looking clause that widens fast the more a pile leans on legends, since so much of a modern black-heavy deck is legendary by default. The cost structure is what keeps the return honest: it is a sacrifice ability, so the 2/3 has to leave the battlefield to fire, and the activation on top of the mana already spent casting it makes the bulk-return a real turn's worth of investment rather than a free loop. What the design is doing is trading a disposable early body for a delayed refuel: you deploy it as a blocker or chump, then cash it in later once the graveyard has filled with legendary threats and legendary value engines that died to removal or a board wipe. Note the distinction that matters for evaluating it: this fills your hand, not your board. The bodies come back as cards to recast, not as reanimation targets landing in play, so the tempo is a two-step (retrieve, then pay again to redeploy) rather than a single swing. The narrower the legend density, the closer this drifts to a vanilla 2/3; the more legend-saturated the deck, the closer it comes to a one-card handful of second casts.
