This deck has been performing unreasonably well for me lately. It has been my primary ladder deck for the past couple weeks, and got me to my first masters, then my first top 100 masters. Shen-Ra is a nonbo with a lot of the cards here, so feel free to substitute your 1-drop of choice if you don't want to shell out for legendaries. She's definitely the optimal choice but not by so much that it isn't fine to switch her for something else.
Any feedback on the market is welcome, I'm really not sure if it is optimal currently.
