Infinite Loops

While most repeatable interactions involve playing or using cards are limited by the Rule of Six, in very rare cases, an infinite loop can occur. Where two or more card abilities will continue to resolve each other repeatedly in a way that is not limited by the Rule of Six, the active player first chooses how many times they want to resolve the loop, then stops resolving the loop. The active player then adjusts the game state by removing the affected card from play and placing it in its owner’s discard pile so play can resume as normal. A card removed from play in this way is not considered to have been destroyed.

Outstanding Issues

There is an outstanding issue concerning Infinite Loops.

• My opponent has multiple creatures in their battleline with more than 3 power as well as Reassembling Automaton. If I play Plague Wind, it causes an infinite loop where Reassembling Automaton is repeatedly destroyed. How should this be resolved?

  Arcana Advises: In this case, the active player resolves the loop as many times as they wish, and then they adjust the game state by removing Reassembling Automaton from play. After adjusting the game state, play can resume as normal.
