If Archfiend of Gilfer is equipped to a monster, does Pandemonium trigger when that monster is destroyed?!
Archfiend of Gilfer is an Equip Spell when equipped.
No. While equipped it is treated as a Spell, so Pandemonium does not trigger.
Does Pandemonium trigger when Archfiend of Gilfer is sent to the Graveyard while equipped to a monster?!
Archfiend of Gilfer is equipped to a monster and is sent to the Graveyard.
No. It is treated as an Equip Spell at that time, not a monster.
