Freeze Trap, Transmute to Butterfly and Frighten to Death. Being able to exhaust that body left behind means you are somewhat nullifying the drawbacks of previously mentioned cards, and threaten direct damage before your opponent gets the chance to play another ally. Of course, it's also very nice that nothing with 2AP or less can defend against Maneater when she attacks. This is great against black, red and green filler decks.
Strong Against: Anything with 2AP or less and low-stat ally decks like Ants Attack.
Weak Against: Aggro and quality decks.
