Hey guys, I have a question. Lyla states "You can change this attack position card to defense position to destroy 1 spell or trap card on the field. You cannot change the battle position of this card until the end of your next turn, except by a card effect." Now I've always played that "not changing the battle position until the end of your next turn" as a side effect as meaningless as Phalanx only activating "once per turn". To clarify that, I would switch it back to attack mode next turn. The way I see it, the effect is only there to keep the effect from going off more than once a turn: for example, Lyla was already on the field, you switch her to def for the effect, then since that was by an effect you could switch her to attack again and bak to def to kill something else. What does it mean by "the end of your next turn"? The end phase? You can't change battle positions in the end phase anyway. And it doesn't prohibit Book from being used so why the end of your next turn an not 2 turns from now? I ask this because someone didn't let me switch her to atk on my next turn so I could switch her to def again. Is he right or am I? I honestly don't know, nor can I find a ruling on it. And someone please explain what exactly the effect means
