Hi, 

So this is the deck I pushed to Legend with for the 1st time. 

Despite everyone claiming Highlander Priest being inconsistent, I had great success with it. 

Against Aggro try to keep as much early Game stuff as possibble in your start hand. 

Vs Midrange/Lategame Decks you can often keep Galakrond and outvalue them.

And of course Zephrys and Alexstrasza are your Playmakers/Value engines/even Lifesavers.

Have fun with the deck.
