This is a 50 spell Moment of Creation deck with Shadow focus. Not a competitive deck but a fun deck. I am having a great time playing it around Masters 500 level in the last days.
The unusual take is that it is including
Madness +
Devour +
Dark Return with the goal of stealing your opponent best units and bringing them back to the board.
Additionally I added
Subvert and
Pilfer that add even more fun to the deck (I specially like to play
Pilfer right after your opponent scouted and kept the card at the top.
Other than that it is a lot of removals and mana spells (Hold your Vara's Favour as much as possible to steal units with Aegis.
I also added
Xenan Augury to help piloting the deck.
It plays very well against decks with focus on big drops (like Big Praxis).
This is a LR deck so if you are playing against anything aggro then you will need to get some drawing luck (like
Devastating Setback), otherwise you will probably lose (be warned, it is probably a bad idea to play this deck in Diamond levels).
Obviously this deck is useless against any opponent playing decks with no units.
Anything else is doable (even Grenadin decks) and a lot of fun. Enjoy!
