[Tales] [Quickcast] Your opponent cannot play cards with total cost greater than the number of magic stones they control. [Enter] >>> Return target spell or non-magic stone entity your opponent controls with total cost equal to or greater than the number of magic stones they control to its owner's hand. If you do, draw a card. [Revolution] If an ability or effect of this card would check the number of magic stones your opponent controls, you may have it refer to that number minus the number of J/rulers they control instead.
