To celebrate having suddenly gone from 1 Niv to all 4 from packs and icrs in less than a week, I built Adrian Sullivan's Jeskai control deck. I blew the few rare WCs I had on treasure maps and the last Clarion, but I'm still missing 2 maps (replaced by azcanta and a chemister's insight), some UW duals, plus a teferi (which became a ral... Much less op).

Oh man, I love it!
It's turbo control! A control deck that wins quickly, wow!

Original list:
3 Teferi, Hero of Dominaria (DAR) 207
2 Enigma Drake (M19) 216
4 Niv-Mizzet, Parun (GRN) 192

1 Spell Pierce (XLN) 81
2 Syncopate (DAR) 67
4 Treasure Map (XLN) 250
4 Clifftop Retreat (DAR) 239
4 Glacial Fortress (XLN) 255
5 Island (XLN) 265

Thanks to CGB for showcasing this sweet list (I was getting really bored of boros/white aggro and the Arclight/drake decks that are all over the place).

Love Niv he is tha friggin Boss!
I gotta update my Jeskai Pile and catch some games with him
Treasure map and spell pierce are really interesting choices.
