pokemon dragon vault booster box 3-Pack Blister (Latios Promo) Dragon Vault Bundle | 5

The first card since Necropotence to completely take over every format at the same time (and did so more successfully than Necropotence)

I certainly prefer the non-holo version in Neo Discovery and would have rather seen that one as the holo: I probably dislike the rainbow rare Umbreon GX a bit more than the rookie card still, but choosing the rainbow rare would be cheating

The Set Booster's dedicated basic land slot will be a foil basic land in 21% of boosters

When choosing a playmat, pick something that will have good contrast, for example

$20 Go Tall Upgrade If you want to focus the deck around Arahbo, Roar of the World, you'll want to focus on going Tall, and take out the Go Wide cards that don't support the theme

One of the biggest pieces of advice that I can give on this topic is to build a network of people who can or will buy foil and foreign cards
