Contemporary rules and errata are followed, with a few exceptions:

Chaos Orb: 1, Tap: Choose a permanent on the battlefield. Flip Chaos Orb onto the battlefield from a height of at least 12 inches. If Chaos Orb flips over completely during the flip, and lands resting on the permanent chosen, destroy that permanent, and then destroy Chaos Orb.
Upon mutual agreement before a match, Chaos Orb can instead read: “1, Tap: Destroy target permanent, and then destroy Chaos Orb.”
