This is an awesome deck Athene has made. I am trying a slightly different variant of it since I don’t have the Warlock legendarys needed. I replaced them with an Alexstrasza and a Ragnaros for now. Working well so far.
How to counter the other classes with it
I like that he doesn’t want to baby sit everyone like others do. Just straight facts one after another. Athene goes pretty fast with the explanation of everything here but honestly if your having trouble following your not ready for Legend. With even a little bit of practice all this becomes fairly clear.
