Idea with the deck is to pick second, then break the board with a variety of board breakers. From there, normal floo lines to clean up the game. Sideboard allows you to switch out going second cards with going first cards if you'd like.
Obvious note: The Pot of Extravagence's should be Pot of Prosperity's. I do not have access to them at this time, but if you are trying to make the deck at full power, that would be an immediate upgrade.
