ガチャを引く

We listed cards and deleted them, now let's add some cards by playing a gacha game. The game must implement the following features

• The player can pull a gacha a limited amount of times
• Card rarity is linked to card rank (SS cards are more rare than C cards)

In particular, here's the probability for each card rarity:

Rank	SS	S	A	B	C
Rarity (%)	5%	10%	20%	30%	35%

Let's start by making a new table in the database to store how many gacha pulls each player has. We need the user id and the number of pulls.
