The gameplan is pretty simple. Play Spire Shadows out of the market ASAP to make most of the deck free, then use Glimpse the Possibilities to overwhelm the opponent with your buffed units. Temple Scribe and Devour are solid maindeck options for extending the combo.
Regarding the market: Azindel is the clincher if you need a bit of extra push against decks with big units or lots of removal. Nahid's Destruction helps prevent you from running dry if you're having trouble getting your Glimpse. Xenan Initiation and Vara's Choice are emergency removal options.
I'm currently winning most games with this deck on Throne.
