Blue Enchanted 7s
This is, in my opinion, one of the most interesting decks I've ever made and played, due to its playstyle and various synergies. Don't let the high average faeria cost fool you, it is a bit cheaper than that because of Wavecrafter and Spring Mochi.
I generally play it like a midrange deck. For land placement, I typically start in the middle, then go to one side. I clear creatures along the way and move towards the opponent's orb.
There's a lot of synergies and abilities to keep in mind while playing the deck, so once you learn how to make good use of them, it's really rewarding. Also, no DLCs required to make this deck!
Hope you enjoy!
