I'm not a Fan of TrinmxxT. If you want another Reducer use Ulrich, because he has the better reduction ability and you don't really care if Uranus and GraksmxxT have their bonus. They are great without it, but your Piranahs are the chars waiting to win their rounds. I could even see you running 5 Piranah and only the great -5 reducers from Sakrohm.
Morphun (Eklore for your next 4 levels)
Dhalia
Selma
Bloodh
Ahkab
Ulrich
Uranus
GraksmxxT
would be my go.
