Sacred Haven of Debauchery

I also played it for a while and quickly realized that fighting against whales is pointless, and there's not much fun in it.

You can more or less farm cards with twinks (and sell them, transferring currency to your main, and then buying what you need with your main). Or join a large region like The North Pacific (specifically with "the"), join a card guild there, and they'll explain everything to you (respect to the people whose enthusiasm keeps this going). But all these attempts to buy cheaper based on luck, and trade somewhere to profit from the difference... aren't worth the effort.

Oh... that's very strange to hear.

It's like hearing this response about playing Heroes:
"Well, you certainly won't be able to compete with experienced players. But go to the Heroesworld forum, there are knowledgeable people there. They'll tell you how to play Jebus. Practice thoroughly, and after some time you'll be able to compete with average players. Although, in general, Jebus is garbage and not worth it."

...

Can't you just play?

I'm not going to compete with whales, and I don't even set such goals for myself. I also don't have multiple accounts in any games. Nevertheless, I enjoy just playing in my own niche. Even with one account, most of the gray, green, and blue cards are quite accessible. And epic and legendary cards are really for whales.

There are over 48,000 green cards from the third season in the game, over 15,000 blue ones, and countless gray ones - you can collect them endlessly.

I'm perfectly happy with this, without any guilds or whales.
