We get Glints and SPS for winning the fight. We can buy cards with Glints. But which ones are worth buying? Common? Rare? Epic? Legendary?
I can forget about Legendary. If I tried hard, I'd barely make enough for one per a season. It would be demotivating to try for a whole season and then get a card that might not be a good fit.
For the price of 1 Legendary Card I can buy 4,666 Epic, or 46,666 Rare, or 233,333 Common. Interesting numbers. Non-decimal among the Legendary Cards and the others. If every higher card was 10x more powerful than the lower one, the Legendary card would eventually pay off. But I don't think the Legendary card is that strong.
The ratio between Common, Rare and Epic cards is. For the price of 1 Rare you get 5 Common. For the price of 1 Epic, you get 10 Rare.
I'm experimenting. I'm not sure what's more profitable. Anyone care to advise, write your opinion?
