Wow it doesn't work with Fiend Farewell, why? | Archfiend of Gilfer | Deck and Rulings - YuGiOh! Duel Links

It won't work if you're against hazy or other monsters with target immunity effect.

It was against a Tiki Soul.

Because it’s been sent to the grave by a skill

This card has a "timing" requirement like pinch hopper. You need to get it on field, then has it sent to GV by battle.

Damn, I had an idea for an OTK Woodland Sprite deck with this and Fiend Farewell. No dice there. Oh well!

This card don't need to be on the field before send it to the GY to activate its effect

Archfiend of Gilfer being sent to the graveyard has a "When you can" effect, meaning that it can miss the timing. A "when you can" effect must be the last thing to happen for its effect to activate.

Look up "Missing the Timing" and "Archfiend of Gilfer" on Yugioh Wikia for more info.
