Those three points, in particular 1 and 3 would see me try Survival mode and very likely go to the market to build up multiples of summoners and key cards for Bronze or Silver level, I mean with CL prices as they are, why wouldn't I ?
Up to now I have not played Survival mode for two reasons, firstly I have only one real viable deck, my additional cards, particularly summoners are not viable for any kind of run at Survival and they live in my rental account. Secondly, I can't risk losing my cards from my deck for Brawls or ranked ( Mainly Brawls as I have a responsibility to fill a Brawl fray,ranked play is more "optional")
Those are solid suggestions.
I feel a bit left out of Survival, and seeing as I've dropped in excess of $20k into this game in the last four years, I think that is definitely a bit of a "miss"
