YS02-JP001 Odd-Eyes Revolution Dragon
Q: Can I target Odd-Eyes Revolution Dragon with the effect of Pendulum Switch that Special Summons a Pendulum Monster from the Pendulum Zone? Also, can I target Odd-Eyes Revolution Dragon the effect of Pendulum Switch that places a Pendulum Monster in the Pendulum Zone?
A: Odd-Eyes Pendulum Dragon is a monster that cannot be Special Summoned, except by Pendulum Summon from the hand or by its own procedure of Tributing 1 Dragon-Type Fusion, Synchro, and Xyz Monster, so it cannot be targeted with the effect of Pendulum Switch that Special Summons a Pendulum Monster from the Pendulum Zone. Also, an Odd-Eyes Revolution Dragon in the Monster Zone can be targeted with the effect of Pendulum Switch that places a Pendulum Monster in the Pendulum Zone.

Q: Can the monster effect of Odd-Eyes Revolution Dragon that shuffles all other cards on the field and in the Graveyards into the Deck be activated if either player does not have at least 1 card on their field or in their Graveyard?
A: The monster effect of Odd-Eyes Revolution Dragon can be activated if at least 1 other card exists on either side of the field or in either Graveyard, even if there are no cards in some of those locations. For example, if there are no cards in either player’s Graveyard and Odd-Eyes Revolution Dragon is the only card on the field, you cannot activate its effect. If there are no cards in your Graveyard but 2 cards in your opponent’s Graveyard, you can activate its effect.

17PR-JP008 Mudragon of the Swamp
Q: Mudragon of the Swamp requires 2 monsters with the same Attribute but different Types as Fusion Materials, but can it be Fusion Summoned using a face-up Elemental Mistress Doriado and King of the Swamp as Fusion Materials?
A: King of the Swamp is a WATER Aqua-Type monster, while Elemental Mistress Doriado is a LIGHT Spellcaster-Type monster whose effect also treats it as a WIND, WATER, FIRE, and EARTH monster while face-up on the field. Therefore, since they are both monsters with the same Attribute but different Types, they can be used as materials for the Fusion Summon of Mudragon of the Swamp.

Q: Mudragon of the Swamp is face-up in my opponent’s Monster Zone, and its effect that prevents me from targeting it and monsters with the same Attribute is applying. In this situation, can I activate Call of the Haunted targeting a WATER monster in my Graveyard?
A: Call of the Haunted is a card that continuously targets the monster Special Summoned by its effect, but it is not activated by targeting a monster on the field. Therefore, even if the effect of your opponent’s Mudragon of the Swamp is applying, you can activate Call of the Haunted and target monsters with the same Attribute as it.

A: The effect of Tin Musical Battlemech that treats the Synchro Summoned monster as a Tuner is not an effect gained by that Synchro Summoned monster as its own effect. Therefore, even if that Synchro Summoned monster’s effects are negated by Skill Drain, it will still be treated as a Tuner.

Q: There are 14 cards in my opponent’s Extra Deck and 15 cards in mine, including Linklebell. In this situation, can I Link Summon Linklebell using 2 Pendulum Monsters on my field as materials?
A: Linklebell cannot be Link Summoned unless you have 3 or more cards in your Extra Deck than your opponent. When using Pendulum Monsters on the field as materials for a Link Summon, they are added face-up to the Extra Deck instead of being sent to the Graveyard, but in this scenario, you do not have 3 or more cards in your Extra Deck than your opponent when you try to Link Summon. Therefore, in this case, even if you use Pendulum Monsters as materials, you cannot Link Summon Linklebell.
