Brotherhood of the Fire Fist - Raven

The effect "If this card is sent from the field to the Graveyard: You can choose 1 'Fire Formation' Spell Card from your Deck and Set it to your field" is a Trigger Effect. (This effect does not target. It can also be activated during the Damage Step.)

When applying the effect "If this card is sent from the field to the Graveyard: You can choose 1 'Fire Formation' Spell Card from your Deck and Set it to your field," the zone where the chosen "Fire Formation" Spell Card is Set is chosen at the time the effect resolves.

The effect "While this card is face-up on the field, 'Fire Formation' Spell/Trap Cards you control cannot be destroyed by your opponent's card effects" is a Continuous Effect.

The effect "'Fire Formation' Spell/Trap Cards you control cannot be destroyed by your opponent's card effects" is an effect applied to "Fire Formation" Spell/Trap Cards that are face-up on your field. ("Fire Formation" Spell/Trap Cards that are Set on your field can still be destroyed by card effects as normal.)
