1. If a series of effects form a repeating loop that cannot be voluntarily ended by either player, the game ends as a draw.
2. A player can have a series of voluntary actions repeat automatically. To do this, they must demonstrate the series and pick a number of times they want it to occur (infinity cannot be picked). Then, their opponent can interrupt the loop any number of times and at any point if they want to respond. They do this by saying for example “After 15 times, I respond to that ability by playing a card.” After the response, the loop continues until it is complete.
3. If a loop involves the voluntary actions of both players, they first must demonstrate the loop. The loop is complete when the next action a player would take is identical to their first action. Then, the active player picks a number, followed by their opponent. The loop is repeated the lesser number of times (if 0 is picked, no repetitions occur). However, during the last repetition of the loop the active player may choose
any point in the loop at which to stop (this includes not taking any of the actions in the last repetition).
