Q: If I have applied the effect of Synchro Material to a Phantom King Hydride that my opponent controls, can it be treated as a non-Tuner for a Synchro Summon?

Q: If Solemn Judgment negates the Summon of a monster and destroys it, will the effect of Supply Squad activate?
A: A monster whose Summon is negated and is destroyed by Solemn Judgment is not treated as a monster that was destroyed while you controlled it, so the effect of Supply Squad will not activate.

Q: While the effect of Thunder King Rai-Oh is applying, can the effect of Bujintei Susanowo be activated?
A: Even while the effect of Thunder King Rai-Oh is applying, the effect of Bujintei Susanowo can be activated. When resolving this effect, if Thunder King Rai-Oh is still on the field, you will send a “Bujin” monster from your Deck to the Graveyard. (You cannot add one from your Deck to your hand.) This will also apply if Call of the Haunted is chained to the effect of Bujintei Susanowo, Special Summoning Thunder King Rai-Oh.

Q: While the effect of Macro Cosmos is applying, can the effect of Bujintei Susanowo be activated?
A: Even while the effect of Macro Cosmos is applying, the effect of Bujintei Susanowo can be activated. When resolving this effect, if Macro Cosmos is still on the field and you attempt to send the chosen “Bujin” monster to the Graveyard, it will be banished instead. The effect will resolve normally if you choose to add it to your hand instead. This will also apply if Macro Cosmos is chained to the effect of Bujintei Susanowo.

Q: Can I Special Summon Photon Thrasher from my Deck with Accellight?
A: No, you cannot. Photon Thrasher is a Special Summon-only monster, so it must first be Special Summoned through the method described in its text.
http://www.db.yugioh-card.com/yugiohdb/faq_search.action?ope=5&fid=46&keyword=&tag=0
Q: Can Accellight be activated if I do not have both a Level 4 or lower “Photon” monster and a Level 4 or lower “Galaxy” monsters in my Deck?
A: If it is possible to Special Summon 1 Level 4 or lower “Photon” or “Galaxy” monster from your Deck, you can activate Accellight. (Even if you only have one or the other, you can still activate Accellight.)
http://www.db.yugioh-card.com/yugiohdb/faq_search.action?ope=5&fid=20&keyword=&tag=0
Q: If I activated Accellight or Hidden Armory this turn, so that cannot Normal Summon/Set, can I then activate Double Summon this turn?
A: No, you cannot.

Q: If the second effect of Orea, the Sylvan High Arbiter is activated, and a Plant-Type and Dragon-Type monster are excavated, are they both sent to the Graveyard?
A: When the effect of Orea, the Sylvan High Arbiter excavates cards, if any Plant-Type monsters are excavated, only those Plant-Type monsters are sent to the Graveyard. Therefore, in this case, only the Plant-Type monster is sent to the Graveyard, while the Dragon-Type monster is placed on the bottom of the Deck.

Q: During my opponent’s turn, if my opponent attacks my Decoy Dragon and its effect is activated, and I chain the effect of Electromagnetic Turtle, how does each effect resolve?
A: In this case, due to the effect of Electromagnetic Turtle resolving, the effect of Decoy Dragon resolves during the End Step of the Battle Phase. The targeted Dragon-Type monster is still Special Summoned from your Graveyard, but because the attack is completed, you do not perform damage calculation.

Q: If Dragonecro Nethersoul Dragon battles a Dark Soul Token, will the effect of Dragonecro Nethersoul Dragon activate at the end of the Damage Step?
A: Even if Dragonecro Nethersoul Dragon battles a Dark Soul Token, its effect will activate. Since the Dark Soul Token does not have an original Level, the effect of Dragonecro Nethersoul Dragon will make the Token’s ATK become 0, but it will not Special Summon its own Dark Soul Token.
http://www.db.yugioh-card.com/yugiohdb/faq_search.action?ope=5&fid=121&keyword=&tag=0
(Note: Dragonecro Nethersoul Dragon isn’t supposed to have “if this card battled a monster that has an original Level” in its text, as it does here, which explains why it works this way.)
Q: Can the effect of Junk Collector be activated by banishing Blasting Fuse?
A: No, it cannot.

Q: Does the Continuous Effect of a monster start a chain?
A: Continuous Effects, unlike Ignition, Trigger, and Quick Effects, do not start chains.

Q: While the effect of Soul Drain is applying, will a Gemini monster in the Graveyard such as Elemental HERO Neos Alius still be treated as a Normal Monster?
A: The effect of a Gemini monster that treats it as a Normal Monster while on the field or in the Graveyard is not one that activates. Therefore, while Soul Drain is applying, a Gemini monster in the Graveyard such as Elemental HERO Neos Alius will still be treated as a Normal Monster.
