Today, I didn't get very good pulls from the legendary pack, probably a loss of about 53u. As expected, you can't be too FOMO. The legendary pack has a high-value jackpot, but only a 25% chance of breaking even, which is somewhat similar to leverage in contracts—higher risk. I plan not to open packs immediately next time; I'll wait until the card pack count drops below 500 before buying. Although it's just a matter of luck, there are too many C-level cards, and the initial hit rate seems a bit high. Anyway, I'll test it out first.
