Every US Happy Meal Pokémon booster pack contains exactly 4 cards: 1 guaranteed holographic foil card (from the 6 available holos) and 3 non-holo cards (from the 9 non-holos). No duplicate cards appear within the same individual 4-card pack.
Mathematically, collecting all 6 holos with equal odds (1/6) requires an expected 14.7 packs (approx. 15 Happy Meals, or ~$73). Completing the 9 non-holos takes fewer packs since you receive 3 non-holos per meal, making the 6 holos the true master set bottleneck.
