This deck aims to catch your opponent off guard by going blind second. If you lose the dice roll and your opponent goes first, you're perfectly set up. If they go second then you still have the Floo engine to play from, with extra consistency cards like Terraforming, and the pots.
In game 2 if you think your opponent will go second or if you elect to go first, you can swap out the going second cards for D-barrier, Feather Storm, Anti-Spell, and Trap Trick.
I put D-Shifter in the side as it's a dead card vs Kashtira and the mirror match up, but is a valuable option should you face the new tear or other decks that require effects in the GY.
