Removing Hierarch slows you down, but also increases the threat density of the deck. This is important since more of our creatures are now going to be picked off by StP/PtE + SCM on the rebound. Stoneblade also brings in Wrath, which the mana dorks work against us by committing more to the board.
RUG Delver
+2 Path to Exile
+1 Maze of Ith
-1 Qasali Pridemage
-1 Elspeth, Knight Errant
-1 Stoneforge Mystic or Qasali #2 or Gaddock Teeg
Removing the slower threats for more removal allows us to get to the late game. They key is to dispatch Delver of Secrets before it takes us over. Submerge and Mind Harness are also considerations, which is why leaving at least 1 Pridemage in would be a good idea.
Dredge
+1 Bojuka Bog
+1 Tormod's Crypt
+2 E-Tutor
+2 Path to Exile
-1 Elspeth
-1 Thrun
-3 Qasali Pridemage
-1 Mother of Runes
Removal for Narco/Ichorid, extra G/Y nukers, and taking out the slower threats. Mother has limited applications, and Pridemage has no application aside from beatdown. The games you win will be with Ooze and Knight eating their yard. Watch out for Firestorm.
Burn
-1 Elspeth
-1 Thrun
-1 Terravore (if they aren't running Fetchland builds)
-1 Karakas
+2 Path to Exile (creature heavier versions)
+2 Ethersworn Canonist
Slow them down with Canonist and extra removal. Conserve your life total. Fetch basics. Save Ooze for when you can get a one or more activations before it gets insta-killed; preferably eating Hellspark Elemental. Gaddock Teeg keeps them playing fair. Scryb Ranger can help reduce the susceptibility to Price of Progress. Activating Jitte and not being exposed to Smash to Smithereens is a good strategy. StP your own guys to counter their Bolts

Last card really depends on being on the play or draw. I prefer to always be on the draw with this deck in the mirror for extra cards. The only relevant creatures that you need to kill are Mother of Runes and Knight of the Reliquary. Everything else is a wash. Your life total doesn't matter, so don't bother making blocks. Don't trade Jitte with their Jitte unless you can return it with Witness. SoLS serves a role player by ignoring their Moms/Knights/removal. Don't fire off KotR -> Bog until you absolutely need to. Don't Wasteland them obliviously - use it with purpose; you'll need the extra mana. Flyers are important in this matchup. Elspeth provides necessary Jump to go for the kill. Always look out for a potential to connect with an alpha strike. Expect Maze of Ith when attacking, and be prepared for it. Don't walk into Aven Mindcensor. Be wary of untapped mana sources with no main phase play.
To All
Feel free to suggest alternatives. I may not be utilizing the SB options to their best ability.
