Card Rules: Rulings powered by The Netrep API. You can't use 'Pandemonium' to add a Fusion Monster Archfiend or Synchro Monster Archfiend from the Extra Deck to your hand, like 'Fiend Skull Dragon' or 'Red Dragon Archfiend'. If multiple Archfiends are destroyed at the same time by 'Raigeki', you can only add 1 Archfiend from your Deck to your hand with 'Pandemonium'. When your Archfiends controlled by your opponent are sent to your Graveyard, you can add an Archfiend from your Deck to your hand with 'Pandemonium'. [Re: Archfiend General] If this monster is attacked while in face-down Defense Position, and 'Pandemonium' is not in play, this monster will be destroyed by its effect after Damage Calculation. [Re: Battle-Scarred] If 'Battle-Scarred' and 'Pandemonium' are both active, neither player has to pay for Archfiend costs or for 'Battle-Scarred'. [Re: Desrook Archfiend] While 'Pandemonium' is active, and you have 'Desrook Archfiend' in your hand, and your 'Terrorking Archfiend' is destroyed while on the field, 'Pandemonium' is Step 1 of a chain , but you can use 'Desrook Archfiend' as Step 2 of the chain. Then you would get to Special Summon the 'Terrorking Archfiend' and select a Level 3 or lower Archfiend from your Deck. [Re: Huge Revolution] If your opponent activates 'Huge Revolution' and you have 'Pandemonium Watchbear' and 'Pandemonium', your 'Pandemonium' card is not destroyed. [Re: Mazera DeVille] If you Special Summon 'Mazera DeVille', his effect activates, and your opponent chains 'Mystical Space Typhoon' to destroy 'Pandemonium' in a chain, 'Mazera Deville''s effect disappears because his effect needs 'Pandemonium' on the field when the effect resolves, not just when it activates (just like 'The Agent of Judgment - Saturn'). [Re: Mist Archfiend] The effect of 'Pandemonium' can be activated when 'Mist Archfiend' is destroyed by its own effect. [Re: Pandemonium Watchbear] When your opponent activates 'Huge Revolution' while your 'Pandemonium Watchbear' is on your side of the field, your 'Pandemonium' will not be destroyed. [Re: Pandemonium Watchbear] When your 'Pandemonium' is going to be destroyed by 'Mystical Space Typhoon', you can chain 'Ceasefire' to flip your 'Pandemonium Watchbear' face-up, and 'Pandemonium' will not be destroyed.
