Princess_Power: how do you board vs. DPS?
Storm decks are currently quite homogeneous. So they are unlikely to have Xathrid Swarm or Dark confidant post board (people played Confidant with Gush so they could play it in DPS imo). Jace, Vryn's Prodigy is pretty slow so its probably the next best cut. As for what to bring in, you definitely want both null rods. I also think you want the shattering spree. One spree gives you 6 good outs to defense grid (4 FOW, 1 pierce, 1 spree) and spree can sometimes take out multiple pieces of artifact mana. Wasteland is ok vs DPS. DPS is very short on card advantage so it hates trading resources. But wasteland is not super great since you can mana flood and they always have a basic swamp, and maybe a basic island post-board. Ingot chewer is a consideration post board as another anti-Defense grid measure. But chewer is significantly less powerful than Shattering Spree. (This suggests maybe I should run 2 spree, 3 chewers in the sideboard. Spree is worse than chewer vs shops but I would bring in two sprees vs DPS).
On the draw I would board:
-4 Lightning Bolt
+2 Null Rod
+1 Spree
+1 Wasteland
On the play I usually board:
-4 Lightning Bolt
-1 Jace, Vryn's Prodigy (you can leave in Jace if you expect them to be usually well prepared vs wasteland)
+2 Null Rod
+1 Spree
+2 Wasteland (if you leave in Jace only bring in 1 wasteland)
some thoughts:
-I don't like bringing in Grafdigger's cage v DPS. The card only stops yawgmoth will. Mentor doesn't have a fast clock so storm can often just go Dark Petition->Necro. And They can go off without Yawg will regardless, especially since they can get empty post board (though empty can lose to mentor depending on the board state).
-Even though you board out the bolts vs DPS having them maindeck really helps game1. And I think that game1 is actually your best game vs storm. Game1 you have four flusterstorm, 13 total counters and they don't have many defense grid. Storm gets more out of their sideboard than you do imo (Defense grid is a house and I have no dedicated storm hate since the sideboard is so tight). So to win the mu you really need to focus on winning game1.
-If the deck had green you could run ancient grudges over shattering spree. Ancient grude imo is good enough that you are happy to maindeck it. And with a grudge main and 1-2 in the board the storm mu would be much better. As you could easily pressure their artifact mana and have a great answer to Defense Grid. But this requires changing the deck pretty fundamentally.
-If you actually expect Xathrid swarm I would leave in 2 bolts. And if they have Swarm probably they don't have defense gird (is this true?). So I would board:
-2 bolt
+2 Null Rod
