I have to agree, there's a BIG difference between courage 4 and +4 power. and there's an equally big difference between the 3 damage of Lewis
and 5 damage of Amelia
it's clearly a better card, although it's vulnerable to stop ability she can be used many times against the best cards of the game.
between miss twice and xu58 I think it's all about the deck, in a deck with some high power / low damage cards I would prefer XU52
but if you lack power miss twice can be a good power card with stop ability and poison, she is similar to splata, although her poison is 1 the minimum limit is 1 as opposed to the min 3 of the Freaks
. Of course miss twice is not the greatest card for a lvl 5, but it has good power reasonable damage and bluff ability. Normally I would suggest playing XU52
but miss twice can be a good choice as well
