Personally, I just bring in play set of therapies (naming sfm or jitte if he's already fetched it) and pridemage. Furthermore, Daniel and I had a discussion about harmonic sliver on his recent tourney thread and I'm switching to harmonic sliver since it gives more value when used in conjunction with therapy.
Stoneblade decks are a grindy matchup- I'm not a fan of Cabal Therapies coming in - you want things to recoup lost cards from sweepers and discard.

Sylvan Library is a very good one, and in the same vein I've also used Domri Rade (with a Taiga in the main) who is a huge threat (as early as t2) that is hard for them to deal with. Your own Umezawa's Jitte or 2 is also a great proactive answer to theirs and a big threat. Obviously a Harmonic/Viridian/Pridemage comes in. Gaddock Teeg possibly as he shuts off Verdict, Explosives, Jace, but I think he's pretty marginal. Maybe an Ezuri if you have it, as it is a cheap late-game threat that can beat Verdict/Perish.

I would side-out cards like Crop Rotation, Natural Order, and combo-oriented creatures like 1x Heritage.

I think it becomes trickier with the Deathblade decks who may leave in Geist of Saint Traft (say, if they're on the play) in which they could be very aggressive unlike the usual esper stoneblade.
