Wow, that's very efficient way to grind DEC. My problem in sitting at Silver 1 is lack of power that's why i maximized rentals by renting powerful cards at thesame time will give me much power rating. There are high bcx cards I rented but I know i cant fully maximize due to summoner level. (ex. Frost Giant level4, 48DEC rent with 17K power rating).
Do you have some recommended lineups in S1 or S3 that I can try to play with?
