This Property entry details every card with an effect(s) with a predetermined number of activations per turn per copy, such as "Once per turn", "Up to twice per turn", etc. The difference between "Once per turn" and "The/this effect of '[...]' can only be activated once per turn" is that, in the first case, you can activate the effect once per turn for each copy of the card you may control, while in the second case, even if you control 3 copies of the card, the said effect can be used only once that turn. __TOC__
