I was thinking about having 3 "tiers" of packs. Bronze, Silver, Gold.
![Image](https://image.prntscr.com/image/k5CZC6W3RNGZj1RZIZ9qng.png)
Bronze: 20 Credits (would be the current buy)
15 Cards
10 Common
4 Uncommon
1 Rare
Silver: 30 Credits
12 Cards
6 Common
4 Uncommon
2 Rare
Gold: 40 Credits
8 cards
2 common
2 Uncommon
4 Rare
By design, as the packs go up in class, the amount of cards lower for high credit purchase. But you have a chance at some more rares.
Just an idea as I have never seen this suggestion before. I tried searching for it but didn't find it.
The credits and card amounts are up for debate too. Is this a good idea?
