Hearthstone tournament for Heroes fans.

What does being afraid have to do with it? If not everyone can have legendary cards, then Naxxramas cards shouldn't be available either, except for the free ones. Isn't that right?

Explain to me, what advantage do the cards from Naxxramas give? Yes, there are strong ones: Ghoul, Spiders, Sludge Belcher, etc., but they aren't overpowered, just regular cards...
