Bone Temple Block: Discarding a card is part of the resolution of “Bone Temple Block.” The effects of “Bone Temple Block” happen in sequence, so if you discard “Archfiend of Gilfer,” it will miss the timing on and not activate its effect.

Machina Fortress: Your opponent will miss the timing to activate the effect of “Archfiend of Gilfer” if it is discarded by the effect of “Machina Fortress.”

Power Tool Dragon: If “Macro Cosmos” is active, you can still send an Equip Spell Card to the Graveyard to protect “Power Tool Dragon.” If a Chain resolves with “Power Tool Dragon” being destroyed, and you send “Archfiend of Gilfer” equipped to “Power Tool Dragon” to the Graveyard instead, you can activate the effect of “Archfiend of Gilfer” and re-equip it to a monster on the field (including “Power Tool Dragon”). If you send “Archfiend of Gilfer” equipped to “Power Tool Dragon” to the Graveyard during the middle of a Chain, or in the middle of an effect resolution, then you cannot activate “Archfiend of Gilfer” and reequip it, because you missed the timing.

Exchange of the Spirit: "Exchange of the Spirit" does not "send" cards to the Graveyard; it swaps the cards in your Deck with those in your Graveyard. So the effects of cards like "Archfiend of Gilfer" will not activate

Lone Wolf: "Archfiend of Gilfer" and "Dark Necrofear" in the Graveyard can activate their effects and target "Monk Fighter" targeted by "Lone Wolf". This is because they activate as Monster Cards, equip to the target monster, become treated as Equip Spell Cards, and THEN apply their effects (by which point they are now treated as Equip Spell Cards).
