- If Spatial Collapse is activated, and an effect is chained so that a player has more than 5 cards on the field after Spatial Collapse resolves, the controller selects cards to send to the GY to make the number 5.
- You can activate Spatial Collapse when you have 5 or less cards on the field and your opponent has 5 or less cards on the field.
- Spatial Collapse includes Tokens, too.
- While Spatial Collapse is active and you have 1 or more cards already on your side of the field, you cannot activate Scapegoat because you would have your 1 previous card + the Scapegoat card + 4 monster tokens = 6.
- When you have 4 cards on your side of the field while Spatial Collapse is active, you cannot activate Change of Heart.
- When Cyber Jar is activated while Spatial Collapse is active, if the number of cards exceeds 5, each player selects cards to send to the GY to make the number 5.
- When you have 4 cards on the field and you activate Remove Brainwashing, you select cards to destroy to make the number of cards you control 5.
