Forum:Dragunity phalanx

Dragunity Phalanx reads: "Once per turn, if this card is equipped as an Equip Card to a monster, you can Special Summon it."

I've read that the effect of effect monsters reset in the graveyard. So with Dragunity Phalanx I should be able to use a normal summon of a level four Dragunity, such a Dragunity Dux, then pull Dragunity Phalanx out of the graveyard to equip to Dux. I could then Synchro summon Dragunity Knight Vajrayana. Use her effect to pull Phalanx out again, he special summons, again, then I Syncro summon a level eight. This would seem to go directly against the "once per turn."

I hope someone will be kind enough to clarify this to me so I can make the argument during game play to use this combo.
