Kyo blinked at how quickly the other boy had claimed the cards, a bit too stunned to react himself for the moment. Perhaps he hadn't been as prepared as he thought after all. Either way, at least he was sure of how it worked now. 

Nodding in acknowledgement, he placed his hand back on the top of his stack and started quickly flipping cards over again. Once another pair showed up, he tried to slam his hand down the same way Rez had before. Checking the cards after, he could see that it was a pair if fours this time.
