Format-Specific Errata and Rules

Old School uses the current rules of Magic, with the following exceptions:

Mana Burn

Mana burn still applies in Old School and uses the following rule:

When a step or phase ends, any unused mana left in a player’s mana pool is lost. That player loses 1 life for each 1 mana lost this way. This is called mana burn. Mana burn is loss of life, not damage, so it can’t be prevented or altered by effects that affect damage. This game action doesn’t use the stack.

Additionally, 1 card has format-specific errata in Old School: Chaos Orb.

Chaos Orb – (2)


1, Tap: Choose a nontoken permanent on the battlefield. If Chaos Orb is on the battlefield, flip Chaos Orb onto the battlefield from a height of at least one foot. If Chaos Orb turns over completely at least once during the flip, and lands resting on the chosen permanent, destroy that permanent. Then destroy Chaos Orb.

(NB: Players are allowed a “fair flip” on Chaos Orb, which means they can move the targeted card to the center of the table for the flip.)
