Haxorus is the promotional one here.
Yes! There is a new pokemon card series called Dragons Vault! Really cool in my opinion! In these packs, you get 5 cards. Rip-off? Nope! Each card is a special holographic card SPECIFIC to this series. The only way you can get these cards, is you can get them in special card booster packs that contain:
1 Holographic Promotional Card
3 Pokemon dragons vault card packs
1 Holographic Promotional Card
3 Pokemon dragons vault card packs
