From Senti best cards are Lehane , Tobbie , Jakson , Flinch / Melvin leaving you enough room to improve melanie but i rather pick another clan , berserk gives you sacrifice card lola , soa elvis , stable blocker melanie , and beast spyke most of them suffers against soa so flinch would be a must.
What we would like to have
+ 1 sacrifice card
+ Handle soa better
+ 1 soa , sobs could come in handy
+ Atck manipulation is good too but not as important as sob
I would either go junkz route quibik , gibson , flanagan , veenyle cr or sob azel , pan , edwin , artus
