Hilde IS really good, her problem is surviving long enough to hit like a truck ^^. And in a very agressive meta like the current one it's not too easy, but still doable. Use Shadowar, Stand-Off, maybe Enemies Now Friends (my own little fav trick, cuz killing with a 9-11 damage Pommel Smash after a BIG attack just makes me laugh) and you get damage redux. Against Rasho, Brian Fury and Paid to Protect, use Pommel Smash, Hope for One's People, or hope to hell that your opponents messes up his turn.
Another card that surprised me yesterday was Nobility of the Wolf. That damage boost is nasty.
trane >> Problem is, Dual-Wielding is far from guaranteed. Mess up on one check and it hurts you a lot.
