You have good life summoners collection...It't time you get some of the max life monsters too... Then you wouldn't fear playing or facing life faction.
I had the same fears with life faction like you but got over them by continuously playing and improving my strategies.
Now I am looking at mother khala as she can be useful in Broken shields battle rule.
Good day ...Mango man
I am currently lacking 2 or 3 very important life cards as you noticed. Defender of truth is one of them but at alpha, it is costly to buy atm. Thank you for the support!
