Here is the Mardu control deck I played last Saturday in our local playstore, a list that I have come up with after checking the cards that our teammate JayR got in his Khans of Tarkir booster box. Note that it is a fixed list as compared to the actual cards played so as I would not let you wonder why there is only one-ofs of this or that card. The deck went 3-0 before intentionally losing in Round 4 but still it finished first place.
