Day of Black Sun (TLA 373)

Sorcery • Mana cost: {X}{B}{B} • Avatar: The Last Airbender • Rare

Each creature with mana value X or less loses all abilities until end of turn. Destroy those creatures.

The solar eclipse robbed Firebenders of their ability to firebend, giving Team Avatar an eight-minute window to storm the capital and defeat the Fire Lord.
