Ravnica: Clue Edition: Amzu, Swarm's Hunger Runner-Up: Headliner Scarlett Ravnica: Clue Edition is a small side set released alongside Murders At Karlov Manor
It can be used as an early play that will set up your next turn with an exiled card, or serve as a cantrip in the mid or late game
in fact, chances are it won't even show up in any given game (particularly if you really need it to)
For example, say I attack with [c]Skaab Ruinator[/c] while my opponent controls [c]Tajuru Snarecaster[/c]
Seedborn Muse Untapping all of your permanents has a wide variety of uses, and doing so during each opponents end step can easily bring a game to a close in a short space of time
