Samson Oak Promo at Japan’s SM7a Tournaments! By: Water Pokémon Master Posted 4 months ago to TCG 19 comments As Principal Oak would say, “how Onix-pected!” Those who participate in Japan’s Thunderclap Spark tournaments between July 6th and August 31st will receive a Samson Oak promo! As posted here earlier, the top finishers will receive either a full art or rainbow rare Zekrom-GX promo. Samson Oak – Trainer Supporter Draw 2 cards. If both Active Pokemon are the same type, draw 2 more cards. You may play only 1 Supporter card during your turn (before your attack). Thanks goes to Jake C. and Bangiras for the translations!
