nice slow and steady gains (if 5x your collection value in 6 seasons is considered slow ....), and it seems like your preferred style of play. patiently grinding away.

not sure if it is your style, but if you wanted to go all out, you could sell out a chunk of your cards now and use the dec to rent a killer diamond-level deck and push for champion rewards (120 season chests !!)

rents are soooo cheap right now its very rewarding for anyone who takes the risk. it wont last forever though !
