Chiara and redra are a nice splash in any monoclan deck
Personally I'm not a fan of vermyn n anymore, I would prefer shogunn or even chlora at 4 stars, even though dr cards with massive damage are very tricky to play against if you don't have SOA
massiv is in an interesting card but I would say a little too vulnerable to SOA for my taste, I would rather use b ball
but in the end if this works for you why change it?
nice score and I'm happy to see bangers used at this level, blaaster cr remains a bomb
