If you interest in this game you could invest a little more
I spent about 250-350 DEC to rent cards each day
And I can climb up to Silver 2 with no problem and gain profit too(About 100-150 DEC)
But I suggest you invest more in DEC if you can because you will gain SPS airdrop
so the more dec i have, the more i get airdrop sps ??
