I've been working on a nice Battle of Wits decklist for a fun tourney in a few weeks. My current build has 247 cards with a lot of tutors and cheap draw/cantrips. The mana base looks really janky but is surprisingly pretty strong unless facing heavy LD decks like Suicide Black. I can often goldfish by turn 5 or 6.

// RANDOMNESS 6
4 Call of the Herd
2 Gaea's Blessing
There still are some slots I'm unsure of. Namely, Call of the Herd (included for the nice synergy with Intuition and Quiet Speculation) and Concentrate (2UU seems prohibitive). And there are probably a lot of good cards that can go there I'm unaware of. I'm considering a single Chainer's Edict, to fetch with Quiet Speculation.
My current "sideboard" is
4 Red Elemental Blast
4 Diabolic Edict
3 Disenchant
3 Coffin Purge
1 Enlightened Tutor
Feel free to post your own Battle of Wits deck decklist, I'll appreciate that too as long as you post some thoughts about your choices.
Now I'm back to my shuffle training
