You Know Nothing

Best anti-Greyjoy and melee card of the game. Hard to find a place for it, but never useless! That's good shit!

"The Rains of Castamere"

About sneak attack - can I play sneak attack after playing military and power as my challenges 1&2?

It's probably in the other FAQs, but Sneak Attack doesn't work in Castamere, as it counts all the challenges you've already initiated —
Ser Dontos Hollard

Can Ser Dontos Hollard save Lysa Arryn after her interrupt has triggered? I'm not too sure about the timing here.

Because if he can save he will become a centerpiece in the House Arryn/House Tully deck I'm building right now.

I'm afraid not. "Would be killed" interrupts always happen before "is killed" interrupts. :) —
