Q&A Rulings
- Q: My "Tindangle Acute Cerberus" is in the Extra Monster Zone, and 2 "Tindangle Tokens" Special Summoned by its effect are in my Main Monster Zone. In this situation, if my opponent declares an attack with "Firewall Dragon", but I activate "Metaverse" and use its effect to activate "Euler's Circuit" from my Deck, what happens to the attack?
- A: In this scenario, "Euler's Circuit" was activated when the effect of "Metaverse" resolved, so the effect of "Euler's Circuit" that prevents your opponent's monsters from attacking while you have 3 or more "Tindangle" monsters on your field will start applying. The attack declared by "Firewall Dragon" stops, and damage calculation is not performed. (No replay occurs.)[1]
- Q: I activate the effect of "Euler's Circuit" during my Standby Phase that gives control of a "Tindangle" monster on my field to my opponent, targeting "Tindangle Apostle". When my opponent gains control of my monster this way, which player chooses the Monster Zone to place it in?
- A: When you give your opponent control of your "Tindangle" monster with the effect of "Euler's Circuit", the player who activated the effect of "Euler's Circuit" chooses the Monster Zone to place that monster in.[2]
- Q: If there are no available Main Monster Zones on my opponent's field, can I activate the effect of "Euler's Circuit" that gives my opponent control of a "Tindangle" monster on my field?
- A: The effect of "Euler's Circuit" that gives your opponent control of a "Tindangle" monster on your field cannot be activated if your opponent has no available Main Monster Zones. Furthermore, when resolving that effect of "Euler's Circuit", if your opponent has no available Main Monster Zones, the targeted "Tindangle" monster cannot change control and it is destroyed. (That monster is not treated as being destroyed by a card effect, so even if the destroyed monster is "Tindangle Hound", its effect that activates when it is destroyed by battle or card effect cannot be activated.)[3]
