OCG Rulings

• If you equip multiple "Metalmorph" then each copy will increase the monster's ATK by 300 points. Furthermore, when the monster attacks, the effects that increases its ATK by half of the opponent monster's ATK overlaps. For example if 2 copies of "Metalmorph" are equipped on the same monster then that monster gains 600 ATK, and when it attacks an opponent's monster, it gains ATK equal to 2 X half the ATK of the opponent's monster.^[1]

• You can equip a Trap Card to an opponent's monster, but only if the Trap Card does not specify "your monster". So, you can equip "Metalmorph" to an opponent's monster because it does not specify otherwise, but you cannot equip "Blast with Chain" nor "Kunai with Chain" to an opponent's monster because these cards specify "your monster".^[2]

• Normally, for Normal Trap Cards and Counter Trap Cards, after they are activated and resolve they are destroyed and sent to the Graveyard. Continuous Trap Cards with the "Continuous" icon and Trap Cards like "Metalmorph" and "Blast with Chain" which equip themselves to monsters remain face-up on the field after activation.^[3]
  • The following cards from before Magic Ruler was released on April 20, 2000 do not have the "Continuous" icon, but during the Duel they are still treated as Continuous Trap Cards: "Ultimate Offering", "Royal Decree", "Magical Thorn", "Robbin' Goblin", "Dragon Capture Jar", and "Call of Darkness".^[3]

Mentions in Other Rulings

• Fake Feather: If you activate "Fake Feather" and target "Blast with Chain" or "Metalmorph", then the effect will resolve, but "Fake Feather" will not remain on the field equipped to the target monster.^[4]

• Junk Collector: You cannot activate the effect of "Junk Collector" by removing from play card like "Metalmorph" or "Blast with Chain". You can activate the effect by removing from play "Kunai with Chain", but you can only apply the effect which changes an attacking monster to Defense Position when an opponent's monster declares an attack. You cannot apply the effect which equips it to a monster on your side of the field.^[5]

• Vylon Epsilon: You can send to the Graveyard a Trap Card like "Metalmorph" that is equipped to "Vylon Epsilon" to activate its effect. You can send to the Graveyard an opponent's Equip Spell Card that is equipped to "Vylon Epsilon" to activate its effect.^[6]

Previously Official Rulings

These TCG rulings were issued by Upper Deck Entertainment and have since been deemed unofficial by Konami.[7] They were previously considered official and can still be correct, as long as they follow the official gameplay rules, or unless Konami has issued a ruling that says otherwise.
