Card Rulings:Machine Duplication

OCG Rulings

• This card targets 1 Machine-Type monster you control with 500 or less ATK.

• A Token Monster like "Sheep Token" is treated as a Monster Card on the field, but they do not exist on the Deck. Therefore, since you cannot Special Summon any monster with the same name from your Deck, "Machine Duplication" cannot be activated by targeting a Token Monster.

• When "Genex Recycled" uses its effect and changes its name to "Genex Neutron", if you activate "Machine Duplication" and target "Genex Recycled", then you will Special Summon up to two "Genex Neutron" from your Deck.

• If the targeted monster is no longer face-up on the field when resolving "Machine Duplication" - such as if "Book of Moon" or "Compulsory Evacuation Device" is chained - then you cannot Special Summon any monsters of the same name from your Deck.

• Even if "Stronghold the Moving Fortress" or "Metal Reflect Slime" that is being treated as a Machine-Type by "DNA Surgery" are treated as Monster Cards by their own effects, they are still treated as Trap Cards on the Deck. Therefore, since you cannot Special Summon any monster with the same name from your Deck, "Machine Duplication" cannot be activated by targeting "Stronghold the Moving Fortress" or "Metal Reflect Slime".

• If "Rush Recklessly" is chained to "Machine Duplication" so that the targeted monster has 501 or more ATK at resolution, then you still Special Summon monsters with the same name.

• If "Machine Duplication" targets a Machine-Type monster with 500 or less ATK that has been affected by "Forbidden Lance", then you can still Special Summon monsters with the same name as the Machine-Type monster.

• "Jinzo - Jector" is treated as "Jinzo" while it is face-up on the field or in the Graveyard. Therefore, if a "Jinzo - Jector" whose ATK was halved by "Shrink" is targeted by "Machine Duplication", you can only Special Summon "Jinzo" from your Deck. (You cannot Special Summon "Jinzo - Jector".)

Video games

• The Machine-Type monster is chosen at activation of this card, so if the opponent chains "Ring of Destruction" to destroy the chosen monster, up to 2 copies of that card can still be Special Summoned.

Previously Official Rulings

• If a monster on the field, with an ATK of 500 or less, is changed to Machine-Type with "DNA Surgery", you can use "Machine Duplication" to Special Summon up to 2 copies of it from your Deck.

Mentions in Other Rulings

• Proto-Cyber Dragon: You can use "Machine Duplication" and "Proto-Cyber Dragon" to Special Summon up to 2 "Cyber Dragons" from your Deck. (provided "Proto-Cyber Dragon's" ATK is lowered below 500.)

• Trap Monster: If "Metal Reflect Slime" becomes a Machine-Type Monster with "DNA Surgery", you can select it with "Machine Duplication" but you will not be able to Special Summon any cards because "Metal Reflect Slime" is a Trap Card while in your Deck.
