It's a fun game, I recently bought the starter pack and rented some cards. Even though you can technically earn while playing it's the game play and balance that keeps me in a game. I have to say I'm pleasantly surprised, with the block-chain technology still being young and it still being a bit like the wild west I didn't expect to play something so fun on it already.
Currently in silver league so I'm still a LONG way from that 0.6 steem per minute. If I had any more money to invest in the game I would, at this point it just seems like a no brainer. I would look to the returns as a way to keep growing my deck. Games like Hearthstone while I enjoyed them the cost was prohibitive to me, I've been injured and mostly hospitalized out of work steady for 10 years now, so my budget for gaming doesn't really exist! With card games that really limits the level you can play at!
Got to thank @aggroed for sharing the speed-run posts by @jacekw it really gave me insight into how I could make the game pay for me and let me gradually play at higher levels without needing to pay with fiat cash.
I'll jump on the discord later after work!
