The breakdown is: 3 Common cards 1 Uncommon card 1 Rare, Holo or better card The hit rate is often higher in Japanese boxes, meaning you can draw a rare or holographic card more often
Mew cards are really, really hot right now on the secondary card market in general, so my pick for the top chase card overall from 30th Celebration is this Mew Futuristic Rare
Nevertheless, you can still beat it sometimes
If you choose to exchange cards for Flair, be sure that you dont need that Pokemon in several decks, or that you wont end up unbalancing a deck you may be using for Pokemon TCG Pocket Battle missions
Whilst all of these chase cards technically have a chance of being pulled from the Latias ex Box, it's a ridiculously slim chance
