My current list is as follows:
4 Show and Tell
4 Sneak Attack
4 Emrakul, the Aeons Torn
3 Griselbrand
4 Brainstorm
3 Ponder
3 Intuition
4 Force of Will
3 Misdirection
3 Flusterstorm
2 Daze
2 Jace, the Mind Sculptor
3 Lotus Petal
3 Volcanic Island
3 Island
1 Mountain
3 Ancient Tomb
2 City of Traitors
4 Scalding Tarn
2 Misty Rainforest
18 Lands, 7 Cantrips, 2 'out'-spots and Flusterstorms maindeck are usually the points of criticism people have for my build.
18 Lands have served me very well so far, once in a blue moon will I find myself in need of a land, but as of yet, not often enough to warrant a 19th land.
As for the cantrips, I cut one of them and one creature for my two 'out'-spots, currently Jace 2.0. While I certainly appreciate the need for cantrips to assemble the combo, I also see a need for outs main and with Griselbrand our likelyhood of finding said outs increases greatly.
I am currently running 2 Jace as I went to a tournament where I did not think there were any reanimator or other show & tell decks, thus Ensnaring Bridge and Humility were not deemed to be very likely cards on the opponent's side of the board. In that tournament (which I won 6-0) Jace really proved himself to me; he was not only exellent counter-bait (which wouldn't really warrant a place in the deck) but in the cases where he was allowed to hit the board he also greatly improved my own board position. Against control he let me brainstorm and fateseal my way to an exellent hand while keeping the opponent's hand worse for wear and against aggro he bought a turn or two by bouncing and then taking a turn's worth of punishment. In another meta I would probably play Chaos Warp instead so that I'm able to draw 14 with Griselbrand to remove a bridge or similarly.
My input for Flusterstorms main:
I don't really find them too narrow, the spells I really care about are the opponent's counterspells (which it hits with great grace) and the opponent's discard spells (which is also hits quite well). While other spells CAN be dangerous - looking at you Knight - I still have 4 Force of Wills and 2 Daze for them, while having 6 more counters for the spells I really find threatening. I've very rarely come across a situation with this deck where I held a Flusterstorm and truly wished it was a Spell Pierce, maybe against a vial or a planeswalker when I Show'd a creature. However, in that scenario I'd most likely have either 1, exhausted my counters for the Show & Tell anyway or 2, been able to save a relevant counter for the opponent's hail mary pass (as I'd be more likely to try to save a FoW than a Flusterstorm if the Storm count was sufficient)
Chalice has a bit of an awkward relationship with this deck I think, a chalice on 2 would be lovely, sadly that usually drops a bit too late. Chalice at one slows us down to a crawl as we can no longer dig efficiently (it does make Flusterstorm better than Spell Pierce though). Chalice at 0 just feels pretty bad against most decks.. I'd rather just play Blood Moon really =)
Those are my 2 cents anyway.
