Get out a couple Servos and sacrifice them to Divergent Transformations to dig up
Niv-Mizzet, Parun
and
Tandem Lookout
to draw your deck, ping everyone to death, and finish them off with an
Isochron Scepter
combo. Because Niv-Mizzet and Tandem Lookout are the only creatures in the deck, you're guaranteed to get them via Divergent Transformations.
In doing this, every time you draw a card, Niv-Mizzet will deal 1 damage to any target, and if he deals damage to an opponent, you draw a card due to Tandem Lookout's Soulbond effect. This is not a may-- the combo will repeat until you deck yourself if you are not careful. You can end this combo, however! Simply direct the damage at an opponent's creature, planeswalker, or even Niv-Mizzet himself-- or yourself. This is important because you will not be able to kill the table with this combo alone-- but it will draw you into a finisher. So use this combo to eliminate the biggest threats at the table and then move into the a finisher.
Finishers in this deck revolve primarily around using the Dramatic Scepter combo with 2 or more mana rocks available (don't forget you can use Saheeli to turn one of your servos into a mana rock!) to cast an infinite number of spells. With Saheeli available, this allows you to amass an unlimited number of servos so you don't really need anything beyond that (except waiting a turn so they can all swing, but that's a worst-case scenario).
- Isochron Scepter +
Dramatic Reversal
+ Saheeli = infinite servos (all combos below imply Saheeli is active)
- Isochron Scepter + Dramatic Reversal +
Altar of the Brood
= infinite mill as Altar triggers with each Servo entering the battlefield
- Isochron Scepter + Dramatic Reversal + Ghirapur Aether Hub = infinite ping with infinite servos
Saheeli-less Scepter combos:
- Isochron Scepter/Dramatic Reversal + Copy Artifact/Lightning Bolt - Copy the Scepter and imprint Lightning Bolt onto it. This will allow you to deal an unlimited amount of damage.
You can also put cards like Brainstorm, Swan Song, etc onto the copied Scepter.
I've been toying around with adding
Jace, Wielder of Mysteries
to have a win condition where infinite mana is not necessary and the Scepter combo can be skipped-- just draw out your deck with Niv-Mizzet and win.
I've also been considering adding
Feldon's Cane
to the deck-- cast it, copy it with Saheeli, and this way you'll be able to continue to ping people with Niv-Mizzet. Not sure if it's deterministic? I'm thinking of adding it anyway simply in case Niv-Mizzet or Tandem Lookout get milled/removed.
