Chaos Orb

The Chaos Orb was a powerful artifact used by the planeswalker Ravidel that blasted all of the ports in Arathoxia during his invasion of the city, killing Marshal Bikov.

Tournament use
As one of the manual dexterity cards Chaos Orb is banned in sanctioned constructed formats including Vintage.

Rumor has it that a player won a tournament by tearing a Chaos Orb into pieces in order to destroy all of their opponent's permanents, inspiring the creation of Chaos Confetti.
