First of all, if the card is thick, then there is a certain probability that it is a good card. If the cards are thin, it means that there are no good cards, so learn to touch the cards. If it tastes like mocha, it's easy. You just need to see if there is any contrast in the back, and then nail it hard, and then it will be a good card. The second method is to look at the hole, which is also very useful, because 13 was used to look at the hole of the 22nd bullet, so I think this method is also very useful. The third option is simpler. First of all, you need to buy a box, try it yourself, then see which package the card slot is in, then go to the mall to buy it, and then choose the same location, so there is a certain probability that you can draw a full star card. If you want to choose a slot for an Altman card, it's easy. First of all, you have to choose a bag in the first three rows, a bag in the last three rows and a bag in the front seventh row. Then the probability of getting a good card like this is higher. If there is a card slot. It's just that the bag of cards needs more holes.
