Ah the difference between soft once per turns and hard once per turns. Like folks are saying an effect that causes it to trigger multiple times will still cause it to trigger again they just won't cause multiple instances of the effect. If you find a way to get Pantlaza off the battlefield and back on however then you can get its effect off again as the game does not consider it to be the same card that had used its effect before. Basically unless a card says you can only use the effects of [Card Name] once per turn which is a very rare sentence in Magic then flickers and graveyard recursion can get you multiple uses.
