Card Rulings:Monster Gate


 * If you pick up a Spirit Monster, you cannot Special Summon it and it is sent to the Graveyard.


 * If you pick up a Guardian and don't have the corresponding Equip Spell Card on the field, you cannot Special Summon the Guardian and it is sent to the Graveyard. If you have the corresponding Equip Spell Card, the Guardian is Special Summoned.


 * If you go through your whole Deck without finding a card to pick up, "Monster Gate's" effect is negated and the cards you picked up are shuffled back into the Deck.


 * Your opponent can chain "Royal Oppression's" effect to negate "Monster Gate's" effect.


 * Cards picked up that cannot be Normal Summoned are considered "sent to the Graveyard", not "discarded".


 * If you Special Summon "Dark Magician of Chaos" with "Monster Gate", the effect of "Dark Magician of Chaos" activates, but it activates after "Monster Gate" has fully resolved and sent other picked up cards to the Graveyard, so you can use "Dark Magician of Chaos'" effect to retrieve a Spell Card that was picked up and sent to the Graveyard by "Monster Gate" in the process of searching for the "Dark Magician of Chaos".

Mentions in Other Rulings

 * Infernal Incinerator: This card can be Special Summoned (even from your Deck, with a card like "Monster Gate"). You do not have to discard your hand when you Special Summon this card.


 * Royal Oppression: You can activate the effect of "Royal Oppression" as a chain to "Monster Gate". No cards will be picked up, and no monster will be Special Summoned (The opponent still must have Tributed a monster as a cost).


 * Serial Spell: If you chain "Serial Spell" to "Monster Gate" resolve the effect of "Monster Gate" twice (once for "Serial Spell" and once for "Monster Gate") even though you only pay the cost once (for "Monster Gate").


 * Soul Exchange: You can Tribute the targeted monster for any card that requires a Tribute, or for a Tribute Summon. So you could Tribute it for the effect of "Cannon Soldier", a Ritual Summon, or for the cost of "Monster Gate".
