I consider this Valentine an amazing fighter. She's average, helps in the healing and has the ability to be immensely powerful. I recommend opening the fight with her and just be persistent. Not aggressive, but persistent. I use all countervenoms, in this certain style to keep control of my enemy.
Open fight
Block, attack to build up blockbusters, block, combo, launcher, juggle and the moment I land I use Countervenom: Detox, Countervenom: Sedative. Back up, block, combo launcher juggle and the moment I land use Countervenom: Paralysis, Checkmate Incision. (Possibly EKG flatliner if bleed effect was succesful. )
I like her. My first Valentine. <3
