Since the day that card was spoiled, I was kinda confused and still I am. First of all, it's Leadership, which is not big on low threat heroes (even Sam is 8). Second - it's restricted, for some reason (limit 1 per hero would be better here in my opinion). Its definetely requires multisphered deck, but the most prominent candidate for multisphereing is lore, which has burning brand, which is not even restrcited.
I can definetely see how to use this card, but the way I see it - it requires too much setup/too specific deck, and is simply not worth it. Prove me wrong, please. I'm begging.
