Text: You must be Alister Mordecai. START OF RIVAL’S MOVE Once per Round: Rest your Rival. This Round, 1 of their Crystals becomes Limited (this can only be spent during your Move) and can’t Ready.
FAQs/Rulings
Can multiples of the same card use a "Once per Round" effect?
No. “Once per Round” effects can only be used once each Round across all cards that share a name and tag.
Can I use this card's effect if my Rival's is already Rested?
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.
Who decided which Crystal becomes Limited and can't Ready?
