To make sure I understand the numbers correctly - when looking at the "Lifetime Drop Rates By Rarity," it says Legendaries are 0.9704%.

So if I buy a single booster pack, the odds that it will contain at least 1 legendary card is approximately 0.9704*5 or 4.85%?

And there's about a 1.2% chance that a legendary (or any other card) will be a gold foil?
