Fate Transcending Generations

[Field] (This card remains in your Battle Area until you place another [Field].)

[Permanent] During a battle, when you would pay the cost of an Extra with "Kamehameha" in its card name from your hand with a cost less than or equal to the [Ki] under your Leader, you may switch this card in a Battle Area to Rest Mode instead.

([Ki]: An energy marker placed under a card.)
