Swarm, Being of Bees

Mayhem reframes discard as tempo rather than attrition. Where flashback lets you cast a spell from hand and then recast it from the graveyard, this is a single redemption run through the bin: pitch it to any effect that makes you throw a card away, and it returns for one black mana that same turn. You get the body once, but you choose whether that once comes from your hand or from the yard. The payoff wants a deck built to shed cards on a clock, one that would rather convert a discard into a threat than sit on a stranded card. Flash and flying tighten the window on both ends: instant-speed access on the hard cast and the Mayhem recast means the 2/2 can ambush an attacker, hold up as a combat trick, or drop in at the end of an opponent's turn without ever committing early. The constraint that keeps the recast honest is the timing clause: Mayhem only fires if you discarded the card this turn, so the enabler and the creature have to line up in the same window. Discard it now and neglect to recast, and it is a dead card in the yard: nothing later lets you cast it with Mayhem, because a card already in the graveyard cannot be discarded from hand again. The evasive body is almost incidental once you register how little it costs either way. This is a discard payoff wearing a creature's clothes, not a creature you happened to mill.
