I added scarabs and SoW, those I just missed but fit the theme perfectly.
Rage does not fit exactly, as it also reduces stat as much as it grows, plus it can kill creatures with too low HP.
BB is a closer call, but I would leave it out due to the 6 turn delay making it more of a CC rather than buff.
SoFre is also thematically different, it doesn't actually buff the creatures just randomly the effect of attack.
Adrenaline, hmmm, a bit thematically different, although I can see the argument to include that too, so I did.
Mutation: the upped version was in already and the unupped can be worse or even kill so it does not match the theme.
ps: on the other hand I removed fractal as that adds cards to your hand, which is clearly different -- unlike mitosis / PU which adds new copies right on the field which is a kind of growth.
