Yesterday I bought by first item from the store. The Golden Epic Clover and 3 chests for $5. This got me to thinking. Why not just open a card store and sell individual cards.

You can still run a special and have a Golden epic and chest deals, but this way instead of having to wait for the certain card to be offered you can just but it.
Let me talk about card prices and rarities.

There are 5 tiers of card. Golden Epic, Epic, Rare, Uncommon and Common.

You’ve already set the price per se at $5 for a Golden Epic. Following CCG pricing therefore, Epics are $4, Rare: $2.50, Uncommon: $1 and Commons are 4 for $1

But wait. I opened 10 jeweled chests from gem rewards, and received 1 epic and 5 rare character cards. Now I’m not counting trinkets and buffs. 7 chests sell for $10 in the store. Mathematically that means you pay 15 for 6 cards or $1 for a 40% of a rare character card and a 10% chance of an epic.

No, there are 20 base characters with a total of 60 cards. Now I don’t remember by stats class very much but I think that means you need to draw 60*60*2 packs, which is roughly 7k packs. Every in bulk that’s a lot of money.

1) Sell individual cards as listed above.
2) Offer events packs. Individual character, Golden Epic, packs for all of them etc.
3) Sell batches of buff only and trinket only packs.

I know. In a F2P you want the whale you spends a ton of money. And I don’t know how that’s working out for you, but it seems like you would get more money from more people with a card store.
