Wasteland might be your best friend in this matchup. The sideboard doesn't help very much in my opinon, but here's what I tend to use. Pyrostatic Pillar is usually too little too late against the storm decks of today. Usually, I like to use Thorn of Amethyst or Chalice of the Void. Red Elemental Blast is also quite useful to disrupt cantrips and Mystical Tutor. Another possibility is Pyroclasm in order to wipe out Goblin and Zombie tokens, but at this point, it's probably too antisynergetic.
