Aetherspouts (M15)

Instant

For each attacking creature, its owner puts it on their choice of the top or bottom of their library.

Reliable board wipe for blue control and tempo decks. Aetherspouts handles wide attacks without killing creatures outright, making it ideal against go-wide strategies and token decks where traditional removal falls short. The flexibility of letting opponents choose top or bottom is a minor drawback, but the instant speed and ability to reset the board while leaving your own creatures untouched makes it a solid inclusion in Commander control shells and Pioneer/Modern tempo lists looking for unconventional answers to combat-heavy matchups.
