Limiter Removal to a Unioned Machina

Limiter Removal = "Double the ATK of all face-up Machine-Type monsters you control. Until the end of this turn. Destroy All Monsters that was affected by this effect"
Machina Gearframe = "Once per turn, during your Main Phase, you can equip this card to a Machine-Type monster you control as an Equip Card, OR unequip it to Special Summon this card in face-up Attack Position. If the union card would be destroyed, destroy this card instead"

Situation:
On my field I have "Machina Gearframe" and "Machina Fortress" in Face-up ATK position. It's currently my M1 (Main Phase 1) so I used Limiter Removal, so the two of em got doubled ATK, I proceed to BP and calculated the damage to the opponent. Now I proceed to M2 (Main Phase 2) and equipped "Machina Gearframe" to "Machina Fortress" (Union) Then I end my turn.

Problem:
Will the Machina gearframe also be destroyed? due to the effect of the Limiter Removal?


Thanks in advance~!

1) Gearframe will protect Fortress from Limiter Removal.

2) Since Gearframe is not monster anymore, Limiter Removal cannot destroy Gearframe.

Yup thats what will hapens !

Woot =D. But just to clarify what they said, Gearframe will be destroyed because it was protecting Fortress

Tell me you want me to close this !

btw, fortress will stay with 5000 atk till it is destroyed :O
