Ok well really you have used a huge amount of strs on that half deck 15/25
So you have 10 stars to work with which is in general 2 3* cards and 2 2* cards ok
Persoanlly i'd change your uppers but if you insist on keeping that half deck try
All Stars
Robb (soon to be CR)
Randy
Stacey
Jessie
Strong effective and brutal
Junks
Jiro
Tremorph
Gil
2* of your choice Dr or + life
You don't ahve much room to play with when you take 15*s up in half you deck
