Forum:Leyvaten Special summoned on opponent field

As a Example: If my opponent activates Monster Reborn and Special Summon my Dragunity Arma Leyvaten then uses the effect to equip a Dragon to Dragunity Arma Leyvaten then I Sakuretsu Armor the Leyvaten when it attacks me the effect "When this card is sent to the graveyard by your opponent's card effect." does activate in my graveyard? I mean, I get special summonned on my side of the field the dragon equipped to leyvaten by my opponent?
