Okay, I guess I don't have to say much about the gameplan here. Control the board in the early game with Defiance and Hailstorm. Make the keycards of your opponents unplayable with Turn to Seed or Rain of Frogs from the market. Draw as many cards as possible and survive until the turn of Svetya's Sanctum and keep your face aegis.
The ShiftstonedEternal Power Calculator is a deck-building tool that visualizes your odds of drawing enough Influence and Power based specifically on the cards found in your deck.
Most of my matches was against aggro or midrange. So i focused the market more to that. But feel free to add Scourge if you come up against many control decks.
