Further Ways to improve my barebones combo ?

i’m just a new player and i know this combo is well known or whatever but still
i use :
Fallen Carnage, Unicorn Vivifier, Any Creature with low health (call him B)

so the carnage attacks B that dies easly because of his low HP and gives full HP to fallen carnage as well as an extra turn, then the unicorn revives the creature and it keeps on going for an unkillable carnage

any idea on how to improve this ?

Edit:messed up the ability

Why would this make your Carnage OP? It’s affect just makes it get 100% health and then attack again? It doesn’t steal stats? o.o

oh damn, i forgot, i mixed it up with some other ability that gives you 50 percent of the targets attack and defense
gotta edit the post now
