509.4. At high OPL, a player can reverse their most recent action and make a different decision for that action (including not taking it at all) if no new action has been taken by either player, a judge allows it, and the following is true:
509.4.a. The player wants to make a different decision for a spell or ability immediately after all choices have been made and communicated for putting it onto the chain. Example:
509.4.a.1. A player plays Discipline indicating a unit. They immediately change their mind and choose a different unit, or choose not to play the Discipline at all.
509.4.b. The player wants to make a different decision for playing a unit or gear immediately after playing it to a location. Example:
509.4.b.1. A player plays Traveling Merchant to Reaver's Row. They immediately change their mind and choose to play it to their base instead, or choose not to play it at all.
509.4.c. The player wants to make a different decision immediately after making a choice such as moving a unit to a location or discarding a card. Example:
509.4.d. The player wants to undo a decision to exhaust or recycle runes.
509.4.d.1. A player exhausts two Calm runes. Before taking a new game action, the player decides they do not want to exhaust them, and readies them.
