Does the Colossal Fighter + Armory Arm combo work in Edison, and does Interplanetary Invader "A" trigger if it is returned to the Deck?!

You resolve the Colossal Fighter + Armory Arm loop and separately discuss Interplanetary Invader "A" being returned to the Deck by Grave Protector.
Yes, the Colossal Fighter + Armory Arm combo works in Edison. Interplanetary Invader "A" only triggers if it is destroyed or removed from play and remains in a public location; if it is returned to the Deck by Grave Protector, it does not activate. This is treated as an exception related to trigger recognition in private locations.

●Grave Protector's effect is not applied to itself when it is destroyed as a result of battle.
●Effects like Mystic Tomato, etc., are not activated while Grave Protector is face-up on the field.
●A monster destroyed by Dark Magician of Chaos or Lesser Fiend is returned to the Deck instead of being removed from play.
●A monster that battles with D. D. Warrior Lady is still removed from play even if Grave Protector is on the field (if D. D. Warrior Lady's effect is activated).
●If Banisher of the Light and Grave Protector are both active, destroyed monsters are removed from play.
●When there is a face-up Grave Protector on the field and a face-down Desertapir is attacked, and Desertapir’s Flip Effect flips Grave Protector face-down, the Desertapir is sent to the GY at the end of the Damage Step instead of to the Deck.
●If Grave Protector is on the field, the effect of Slate Warrior that reduces the ATK and DEF of the monster that destroys Slate Warrior is still applied, even though Slate Warrior is shuffled back into the Deck instead of being sent to the GY. The timing of Slate Warrior’s effect is still at the end of the Damage Step (when monsters are normally sent to the GY after battle).
●If Grave Protector is on the field when a monster like Black Luster Soldier - Envoy of the Beginning or Great Dezard (with an effect based on when they destroy a monster in battle) battles and destroys a monster, then the Great Dezard, etc., still gets the reward for destroying the monster even though the destroyed monster was shuffled into the Deck instead of being sent to the GY.
●If Grave Protector is on the field, a monster destroyed by Sword Hunter is shuffled into the Deck instead of becoming an Equip Spell Card.
