Herald of the Host is essentially an upgraded version of the classic Serra Angel. The upgrade here is the Myriad mechanic. When a creature with Myriad attacks, for each other opponent, you create a copy of that creature attacking that opponent or a planeswalker that opponent controls. While Herald of the Host isn’t incredibly exciting on her own, potentially having four copies attacking at once seems pretty sweet.
As Angels are an extremely popular tribe in Magic, the Herald of the Host should show up in a number of Angel tribal Commander decks, including Gisela, Blade of Goldnight and Kaalia of the Vast decks, which might find the Herald a functional upgrade over Serra Angel. However, in the case of Kaalia, Myriad doesn’t activate when a creature is put into play already tapped and attacking, as would be the case with Kaalia’s ability.
While she hasn’t become widely played in Commander or not, Herald of the Host will be sought after by Angel card collectors everywhere. There have been decks that certainly found a space for her, although not always Angel-themed decks as you might imagine. Commanders that have adopted the Herald include Lyra Dawnbringer, Marisi, Breaker of the Coil, Kalemne, Disciple of Iroas, Trostani, Selesnya’s Voice, and Ghired, Conclave Elite.
