Text: ATTACK Once per Round, when I’m defended: I can Ready 1 of my Crystals, but until the end of this Round, it’s Limited. (This can only be spent during your Move.)
FAQs/Rulings
If my Rival defends against my attack and I use a card effect to remove that defender from the Combat Area, can I still use my effect?
Yes, you can.
How do I know/how can I show a Crystal is "Limited?"
Crystal cards have a “Limited” back-side, so flipping a Crystal over will show it’s Limited status.
