A new video posted to the Japanese Pokemon Card channel has Professor Kukui Collection Sun! Thanks to Bangiras for the translation. Collection Sun and Moon officially release this Friday on December 9th, but leaks will very likely be starting soon.
Draw 2 cards. During this turn, your Pokemon’s attacks do 20 more damage to your opponent’s Active Pokemon (before applying Weakness and Resistance).
You may play only 1 Supporter card during your turn (before your attack).
