Q&A Rulings

• Q: My opponent activates "Kaiser Colosseum" while I have 2 monsters in my Monster Zone and my opponent has 1 monster in theirs. In this situation, during my turn, can I activate "Soul Exchange"?

A: Even in this situation, you can activate "Soul Exchange". However, since the effect of your opponent's "Kaiser Colosseum" is applying, you cannot put into play any new monsters if it would result in you controlling more than your opponent. In this scenario, if you Tribute Summon a monster, you cannot Tribute the opponent's monster using the effect of "Soul Exchange"; you must Tribute your own monsters. Furthermore, you cannot Tribute Summon a monster with only 1 Tribute, such as a Level 5 or 6 monster, so you can only Tribute Summon a Level 7 or higher monster by Tributing both your current monsters.

• Q: My opponent activates "Kaiser Colosseum" while my opponent has 1 monster in their Monster Zone, and I have 1 Gemini monster treated as a Normal Monster in my Monster Zone. In this situation, during my turn, can I Normal Summon that Gemini monster again so that it becomes an Effect Monster?

A: In this scenario, both monsters were already on the field when the effect of "Kaiser Colosseum" started applying. The effect of "Kaiser Colosseum" prevents you from putting into play any new monsters if it would result in you controlling more than your opponent. Therefore, you can still Normal Summon a Gemini monster that's already in the Monster Zone.

Previously Official Rulings

• Your opponent can still Flip Summon a monster.

• If there are already more monsters on your opponent's side of the field when you activate "Kaiser Colosseum", nothing happens to your opponent's monsters but your opponent cannot Summon any more. Also, if the number of monsters controlled by "Kaiser Colosseum"'s controller is reduced, the opponent does not have to remove any of his monsters.

• Your opponent cannot use "Monster Reborn", "Scapegoat", etc. while "Kaiser Colosseum" prevents him from placing new monsters. However, your opponent CAN use "Change of Heart", "Snatch Steal", etc.

• If all monsters of "Kaiser Colosseum"'s controller are destroyed, "Kaiser Colosseum"'s effect no longer functions until that player has at least 1 monster again (when the effect re-activates).

• If the player who controls "Kaiser Colosseum" has his only monster taken by the opponent with "Change of Heart", then the opponent can place more monsters because "Kaiser Colosseum"'s effect is no longer active until the player has at least 1 monster again.

• When "Kaiser Colosseum" is active, and "Cyber Jar" is activated, if your opponent would control more monsters than you, your opponent has to destroy monsters equal to the difference; the excess monsters are never actually Summoned and instead are sent from the Deck to the Graveyard (so "Witch of the Black Forest" does not get its effect, etc.). So the monsters are destroyed after they are picked up, but before any monsters are Special Summoned for the effect of "Cyber Jar".

• While you have "Kaiser Colosseum" on the field, your opponent can Tribute Summon, if after the Summon they will control less or an equal number of monsters as you do.
