Unlocked Diamond League; Ready to claim more Soulbound reward cards

Hello beautiful world!
You have already read many post taking soulbound reward card. Really these are phenomenon chords especially summoner. To check the reality I played couple of battle using these cards and first experience was great with Soulbound reward cards. Recently I unlocked Diamond League and almost 10 + Daily Focus each day. Although with couple of defeat again rating is down almost 727. Hope till the end of the season there will be enough reward card from Daily focus chest and season focus chest in wallet. What is your experience with these Soulbound cards? Plz leave your valuable comment in comment box..
Thanks..
