10 Card Draw

"You have completed a special mission; you get 10 card draws as a reward!"

"There are 180 cards in the card pool so you can get 10 of the 180 cards as your reward."

"Warning: You can only select ten cards from the pool only once. Once selected, no changes are allowed!"

The cards then came to life and arranged themselves neatly in the air in front of Lin Huang. There were 10 columns and 18 rows which added up to a total of 180 cards. They were all identical; completely black with a golden question mark in the middle that looked more like a golden burning flame.

Lin Huang initially thought he could pick 10 cards from a pool of 18 cards. If that was the case, the probability of getting better cards would be higher. Now, his options were more and so, the probabilities of getting good cards were no better than a regular card draw.
