Forum:Slacker Magician wording

so slacker magician's wording reads "Once per turn, this card cannot be destroyed by battle. During either player's turn, when a card or effect is activated that targets this face-up card: You can detach 1 Xyz Material from this card; negate the activation, and if you do, destroy that card.", which makes it seem like the "once per turn" only applies to the card not being destroyed by battle. does it also apply to detaching for it's effect? other monsterss make it clear if you can only detach once per turnRbeazt (talk • contribs) 10:07, June 12, 2013 (UTC)
