I'm not sure about the
Flaming Brand. I have two real life Rohan Decks, and I must say, if they would be able to add some Flaming Brands, whis would be really overpowered.
Or imagine that: Islidur, BoH with Narsil and 5 opther artifacts and
Flaming Brand would have the same base strength as the Witch-king (besides that when they would face each other, Isildur would get a nice bonus!), then combine with some Elves and
TLAoEaM and you have a 17 strength Ring-Bearer.
I mean, even without the
Brand, this is pretty scary, but with such Brands in all Decks, Nazzies wouldn't stand any chances at all... and they're my favorite culture... snief...
