Gargoyle Flock

Skyswarm reads like a scaling engine and pointedly refuses to scale: the end-step check asks only whether a creature entered under your control this turn, then hands you exactly one 1/1 flyer whether that turn saw a single dork or a dozen tokens. There is no counting and no volume bonus, only a binary yes-or-no gate that rewards showing up to the board every turn rather than exploding once. That flat trickle points toward a specific kind of shell: cheap creatures, token makers, blink effects, anything that reliably trips the entered-this-turn clause turn after turn. And because each token it makes is itself a creature entering, a flock alongside repeatable enters-the-battlefield triggers feeds those payoffs from its own output, so value compounds through your other permanents even while the token count itself holds steady at one per turn. The Simic pairing suits that patient plan: green supplies the go-wide bodies to keep the trigger fed, blue supplies the flyers-matter and copy effects that turn a slowly widening skyward line into an evasive clock. Its stats are modest and the per-turn reward small in isolation, but as a component of a broader swarm shell, this is a metronome that ticks out one extra flyer every turn you keep playing to the board.
