I rent summoners and other cards 5432.
3 days ago I opened 12 silver chests in the daily quest. There was 1 pack of Chaos.
I sold this Chaos pack on the Hive-Engine exchange for 6 Hive and bought 2700 DEC there.
For 2700 Dec I rented water, life and neutral cards. All cards were gold except summoners. In 2 days I reached the rating of 2510.
My rewards are cards for 20 cents and 36 SPS.
Rewards cost $1.65. I could make $2 if I played longer.
But there will still be chests for the season and I hope I'm lucky there
The main thing is that I saw cool combinations from opponents. For example this combination of cards.
