Imo, wish boards should be as small as possible. E. truth really doesnt handle any problems that EE doesn't handle and this guy's poor SB has been bastardized with all sorts of unnecessarty slots already. I mean:

1x Pulse of the Fields === good
1x Extirpate ===reason to run wish
1x Curfew ==== totally unnecessary with Edict
1x Path to Exile / Diabolic Edict ============ Just run edict.
1x Return to Dust/ DIsmantling Blow ===== wasted slot
2x Faerie Macabre ===== never going to see enough of a 2-of to make a difference
2x Relic of Progenitus ===and vvv
1x Tormnond's Crypt ==== consolidate your hate. 4 Macabre, 2 crypt = you beat reanimator and ichorid
1x Ravenous Trap ==== this is almost never useful... how many times do you really see ichorid? And have this make a difference where extirpate doesn't?
3x Ethersworm Canonist === I prefer counters and MM, but if you're only worried about storm (which judging by the rest of your board is not the case) he's good
1x Crucible of the Worlds ==== weaksauce with only 2 wastelands
0x enlightened tutor ==== this is the second best reason to run wish
0x counterspell-type-cards ==== ????

So I'd run... your MB -1 Path, +1 humility, because it wins games and 7 STP MB is totally unnecessary and:

1 e. tutor
1 Extirpate
1 Pulse (maybe)
1 Edict
1 P2E
3 Negate // MM// Cannonist (I'd go with negate, boarding in counters is such a good strategy against combo and reanimator, but cannonist would be better strictly against combo)
4 Macabre
2 Crypt/relic
1 Crucible

I'd probably also find a way to fit 2 Jace 2.0's in MB. They're such a house against the format right now.
