Hehehe..
Show and tell turn two looks strong. I'm not so sure about sneak attack though. I would try lowering the numbers on your creatures, sneak attacks and big-Jace and replace them with draw/deck manipulation, to avoid dead draws. Running black for confidants and tutors may be the most obvious choice, but splashing red for sneak attack is risky in the meta you're facing. Also: People will probably pack hate for permanent-based combos. Though being an enchantment rather than an artifact helps, sneak attack still has a big, bright bulls-eye painted on it.
Though sneak attack is hilarious, I'm pretty sure straight UB with tinker or oath would be better.
And wheel of fortune will be better for half your opponents than it'll be for you. I wouldn't run it main, at least.
I wish I could face you in The Cave this year. Unfortunately I'll be in another country at the time.
Hi Bearman

I’m not playing in the cave this year. Too busy with work, home and cars. But I will test some against team Jæren with this deck after the tournament
1. Without Sneak Attack it’s not a sneak attack deck…
2. Yes. I could need more draw/deck manipulation… Big Jace helps on this.
3. Confidant? Did you notice the 4 Emrakul, 4 Primus along with 4 5cc and 6 4cc?
4. No, I will not play Oath instead of this. Yes I know it’s stronger.
Just for fun, what would you have played this year if you were in the cave?
?If you're playing Sneak Attack, then why no Emrakul? That's X permanents gone, plus it gets shuffled back in to do it again.
Did you read the OP?
