Dalek Squadron

Myriad is the mechanic that scales an attack with the size of the pod, and pairing it with menace turns that scaling into a genuine board problem. The keyword copies the creature once per additional opponent, each token tapped and attacking a different player (or their planeswalker), so a single swing forks damage across the whole table before those copies vanish at end of combat. That much is standard for myriad. What sharpens it here is menace on the original: the token copies inherit it, meaning every one of those attackers demands at least two blockers, and defenders rarely have that many bodies to spare against a swing they did not choose to enter. The 3/3 body is deliberately modest because the payload is multiplication, not raw stats; a bigger creature would price the mechanic out of the aggressive slot it was built for. The tokens leaving at end of combat is the balancing clause: there is no lingering board, no chip-away value engine, just a burst of parallel pressure that resets each turn and asks you to keep the beatdown coming rather than bank it. A menacing swarm that only exists during your attack step, and only when the table is full.
