I searched for this, but didn't find anything, so sorry if this has been posted before.
I was able to successfully complete Shadow & Flame tonight solo, but only by "ruling" that negative threat was permissible. With it, Gandalf kept the threat low enough to give the deck time to build the playing field until the Balrog engaged. I couldn't find anything in the rule book or errata on this, but assume it's been discussed with Shadow & Flame. Can anyone verify what the correct interpretation? Without this ruling, I'll definitely need to go back to the drawing board on my current deck! I just don't see any way to beat this one solo with my current setup.
Thanks for any help.
