The cheapest official way into Pitch Black — a single 10-card booster pack and a coin or promo card behind a hangsell blister card. UK retail price typically lands around £5 to £6 depending on the retailer, putting it in line with a single loose pack but with the added piece of merchandise.
Single-pack blisters are a strange product category. The maths doesn't favour them if you're opening at any volume — a Booster Bundle or the 3-pack version wins on cost per pack — but they have a specific job. Birthday gifts, treats for kids, a casual lunchtime pickup at WHSmith. For the price of a meal-deal you get a Pitch Black pack and a small extra.
The Pitch Black pack itself contains 10 cards from the set's headlining roster: Mega Darkrai ex, Mega Zeraora ex, Mega Chandelure ex, Mega Excadrill ex, and the supporting trainer pool. Pull rates on a single pack are obviously slim — most pulls are commons and uncommons — but the chance of a Special Illustration Rare from this set's roster keeps each one interesting.
If you're seriously collecting Pitch Black, skip the single-pack blister and go straight to a Booster Bundle. If you're buying for someone else as a low-stakes gift or just want a taste of a set without committing, this is the format that earns its keep. UK availability tends to be solid across Smyths, Argos online, and supermarket TCG aisles.
