If I chain the effect of my Koa’ki Meiru Wall to negate the activation, can I still activate the second effect of Magnet Field?
A: In this scenario, Koa’ki Meiru Wall is Tributed to activate its effect before damage calculation, so the Damage Step ends without damage calculation being performed. In this case, the effect of Magnet Field cannot be activated.

Q: Both players have Magnet Field face-up on their Field Zones. In this situation, my Beta the Electromagnet Warrior attacks my opponent’s face-down Defense Position monster, which is Gamma the Electromagnet Warrior. In this case, since neither monster was destroyed by battle, can either player activate the effect of their Magnet Field?
A: In this scenario, both players’ EARTH Rock-Type monsters were not destroyed by battle, so each player can activate the effect of their Magnet Field. In this case, the turn player’s Magnet Field is Chain Link 1, and their opponent’s Magnet Field is Chain Link 2. (As a result, the effect of Magnet Field that activated as Chain Link 2 resolves first and returns your Beta the Electromagnet Warrior to the hand, then the effect of Magnet Field activated as Chain Link 1 returns your opponent’s Gamma the Electromagnet Warrior to the hand.)

A: When resolving this effect of Imperion Magnum the Superconductive Battlebot, if either Valkyrion the Magna Warrior or Beserkion the Electromagna Warrior are not in your hand or Deck, the effect cannot be applied. (Since no monsters can be Special Summoned in this scenario, the Beserkion the Electromagna Warrior in your Deck is also not Special Summoned.)

Q: A Valkyrion the Magna Warrior and Beserkion the Electromagna Warrior that were Special Summoned by the effect of Imperion Magnum the Superconductive Battlebot are face-up on the field. If either Valkyrion the Magna Warrior or Beserkion the Electromagna Warrior are destroyed by battle and sent to my Graveyard, can I Special Summon them with the effect of Kuribohrn at the end of the Battle Phase?
A: Since the effect of Imperion Magnum the Superconductive Battlebot Special Summons Valkyrion the Magna Warrior and Beserkion the Electromagna Warrior by ignoring their Summoning conditions, if they are then destroyed by battle and sent to the Graveyard, they cannot be Special Summoned by another card effect. Therefore, you cannot activate the effect of a Kuribohrn in your hand by targeting a Valkyrion the Magna Warrior or Beserkion the Electromagna Warrior that were destroyed by battle after being Special Summoned by the effect of Imperion Magnum the Superconductive Battlebot.

Q: If Relinquished uses its own effect to equip a Heavy Mech Support Platform to it, what happens to its ATK and DEF? Furthermore, if Relinquished is treated as a Machine-Type monster by the effect of DNA Surgery, and then Heavy Mech Support Platform equips to it with its own effect, what happens to the ATK and DEF of Relinquished?
A: If Relinquished uses its own effect to equip Heavy Mech Support Platform to it, its effect that makes its ATK and DEF become equal to the equipped monster’s, as well as the effect of Heavy Mech Support Platform that increases the equipped monster’s ATK and DEF by 500, are both applied. In this case, the ATK and DEF of Relinquished will each become 1000. Furthermore, if Heavy Mech Support Platform uses its own effect to equip to a Relinquished treated as a Machine-Type monster, only the effect of Heavy Mech Support Platform that increases the equipped monster’s ATK and DEF is applied, so the ATK and DEF of Relinquished will each become 1000.

This set of rulings above summarizes the changes to the Union mechanics. These Union monsters can now be equipped more than one at a time, and their effects are applied even if equipped by other monsters such as Relinquished or Union Rider. Furthermore, you can Special Summon them in Attack Position or Defense Position. But more importantly, the changes only apply currently to the Union monsters found in this Structure Deck: A-Assault Core, B-Buster Drake, C-Crush Wyvern, Heavy Mech Support Armor, Y-Dragon Head, Z-Metal Tank, and Heavy Mech Support Platform. Other older Union monsters like Koitsu and Vylon Tesseract still use the old mechanics.
Q: If C-Crush Wyvern is equipped to a LIGHT Machine-Type monster by its own effect, can I use Tailor of the Fickle to equip it to another monster on the field?
A: A C-Crush Wyvern treated as an Equip Card can be equipped to another monster by the effect of Tailor of the Fickle. In that case, the other monster must be a face-up LIGHT Machine-Type monster on your field to be the correct target.

(No Union monster is chosen from your Deck.) Note that if the Union monster targeted with Roll Out! is a monster such as Heavy Mech Support Platform, which does not have the same limitation, the effect of Union Hangar is applied normally.

Q: The second effect of Union Hangar is activated, and a Z-Metal Tank is equipped to Y-Dragon Head. During this turn, can the equipped Z-Metal Tank then be Special Summoned with Formation Union?
A: A Union monster that is equipped by the effect of Union Hangar cannot be Special Summoned that turn, not just by its own effect but also by the effects of other cards.

Q: The second effect of Union Hangar is activated, and a Z-Metal Tank is equipped to Y-Dragon Head. During this turn, if Y-Dragon Head and Z-Metal Tank are both banished to Special Summon YZ-Tank Dragon, can the banished Z-Metal Tank then be Special Summoned with D.D.R. – Different Dimension Reincarnation?
A: A Union monster that is equipped by the effect of Union Hangar cannot be Special Summoned that turn, not just by its own effect but also by the effects of other cards. However, in this scenario, Z-Metal Tank is banished after being equipped with the effect of Union Hangar, so it is no longer treated as an Equip Card. Z-Metal Tank can be Special Summoned with D.D.R. – Different Dimension Reincarnation.

Q: ABC-Dragon Buster and X-Head Cannon are both face-up on my field. I activate Fusion Tag targeting X-Head Cannon, and reveal an XYZ-Dragon Cannon in my Extra Deck. In this case, can I banish both monsters to Special Summon AtoZ-Dragon Buster Cannon?
A: AtoZ-Dragon Buster Cannon is Special Summoned by banishing monsters on your field whose original names are ABC-Dragon Buster and XYZ-Dragon Cannon. In this scenario, if the effect of Fusion Tag is applied, the original name of X-Head Cannon does not become XYZ-Dragon Cannon.
