Each Shadow Pack contains four English booster packs, one of which has a colored seal indicating its value and rarity:

1 in 20 chance of gold: get a chance to receive packs from the EX era to Wizards of the Coast
1 in 10 chance of silver: receive an XY or Black & White pack
1 in 5 chance of black: guaranteed a Sun & Moon pack
No hit? Then you’ll get a blue pack with Sword & Shield or Scarlet & Violet

The other three packs are standard Scarlet & Violet or Sword & Shield – except when you hit the new Legendary Tier:

1 in 100 chance of the Legendary Tier: all your booster packs are red and contain Sun & Moon or XY packs. You also have a chance to receive a sealed pack from a higher tier.

Experience this unique collection, a true chance to experience vintage, and every pack feels like a surprise.
