Urza's Ruinous Blast

Description

Urza's Ruinous Blast is a legendary sorcery from Dominaria United Commander that carries the legendary supertype. You may cast it only if you control a legendary creature or planeswalker, and it exiles all nonland permanents that aren't legendary. As a high-impact boardwipe in white, it can serve as a control or reset tool in decks built to maintain a legendary permanent.
