The new girls' ability is interesting. It does the same as the Deadly Vipers', but it is not the same ability: if you include 2 Vipers in your deck, that's +100%, just like you include only one of them. But if you include 1 Viper + 1 Gladiatrix, then you have +200% for the gems. It could be useful, but harder to use in the Colosseum, you have to listen more carefully assembling your deck. And I'm really curious how it will work against the Undead Elephant.
