Question: how rare is it to get a legendary from a magical chest?
Answer: However, the Super Magical Chest remains the chest with the highest possible chance of Legendary cards, with a chance of over 50% to get a Legendary card once the Inferno Dragon comes out. It's safe to say that for every 2 Super Magical Chests, or at most, 1000 chests, you will obtain 1 Legendary card.
