Jund : - 4 FOW, -2 Jace, TMS for Disenchant, EE, 2 RIP, SOFI, Surgical Extraction
4c Control: (this i am not too sure how to board): -4 FOW, -2 Spell Pierce for EE, Izzet Statiscaster, 3 Pyroblasts, SOFI
Lands: -2 Lightning bolt, - Supreme Verdict, - 2 Spell Pierce, -1 FOW for 2 RIP, Surgical, Meddling Mage, EE and disenchant
Not sure about the online metagame, but do you consider RIP to be superior to extraction right now? Especially when it negates snapcaster mage and might be tad slow against B/R reanimator.
