Herald of the Host

Myriad is a keyword written for exactly one context: the multiplayer pod, where a single declared attack fans out into pressure aimed at every other seat at once. Against a lone opponent this is a 4/4 flyer with flight and vigilance and nothing more, a fair rate for five mana. Widen the pod to three or four players and each swing conjures a tapped, attacking duplicate pointed at each of the others, all of them resolving in the same combat phase alongside the original: one attack declaration, several potential threats spread across the table (each copy still has to connect, and each can be blocked). Vigilance matters because the original attacks without tapping, so it is available to block on the crackback while still having swung; it is not what makes the trigger recur, since myriad fires anew every time you attack regardless. The exile clause is the load-bearing part of the design. Because the copies vanish at end of combat, myriad never leaves a standing army the way a persistent token-maker like Brimaz, King of Oreskos does; the pressure recurs each turn rather than accumulating into an unbeatable board. It is a tax you levy every combat, not a wall you build once. This is the mechanic in its bare form: no enters-the-battlefield rider, no bonus when a copy connects, just flight, vigilance, and the multiplication, the triggered ability standing alone before any later layering complicated what myriad does.
