I recently attended a Pokemon Sun and Moon TCG Pre-release. At this event you receive a box with four booster packs and some other cards in it to help you build a deck. Each of these boxes comes with one of four special Promo cards stamped with the “Sun&Moon” logo. You then build a deck from the cards you pulled and received and battle against other participating at the event. Each person is given three extra booster packs for participating, and then for every battle you win you get one additional pack. My win/loss record was 2/1 so I got two additional booster packs for a total of 5. You can see me opening these packs, and take a look at the cards I got at the event in the video below.
The promo card we received was the Shiinotic card. There are four different Promos: Bruxish, Shiinotic, Oranguru, and Passimian.
I managed to pull one GX card from the packs we opened. This GX card was Decidueye GX (watch the video to see my reaction). There are three rarities to GX cards, Ultra Rare (which is what we pulled), Full Art (slightly rarer then the Ultra Rare version), and the Secret Rare versions (which are all silver, we saw a few pulled at the event). You can see these rarities in the photo above.
