Before the game, put one "Infinity the Chaos" face down under "the Chaos".
You may use "Chaos" cards, and put monsters up to a total size of "Infinite".
All size 30 or greater monsters on your field cannot be destroyed, and their abilities cannot be nullified, by effects.
This card is treated as a card on your field, it cannot be destroyed, leave the flag area, and its abilities cannot be nullified, and it can attack even if you have monsters on your center!
