Murmuration

Storm Crow, the mascot of a thousand joke threads about the worst creature in Magic, gets promoted to end-step reward here, and the wink is the entire premise. The token clause pays you in the game's most famously mediocre flyer, one per spell cast this turn, which turns a punchline into a genuine payoff: a slow storm count that cashes out into a widening board of 1/2 fliers rather than a single burst. The anthem half quietly does the heavy lifting the joke obscures, since those tokens are Birds and inherit the +1/+1 and vigilance, arriving as 2/3 flying attackers that can swing and still hold the ground. That is the design tension worth naming: a spells-matter engine and a Bird tribal anthem sharing one card, so the token generator feeds its own lord. The end-step timing is the honest limiter; the tokens land after your turn's combat, so the board you build tonight is the offense you commit next turn, and casting spells becomes the fuel rather than the immediate threat. It rewards a deck that wants to chain cheap spells and go wide in the same breath, with the added grin of assembling a literal storm of Storm Crows.
