hobolegs on Saheeli

Think you had mentioned that you already have Cascade Bluffs on the way, and Spire of Industry was a possibility we talked about, and you might want to consider Castle Vantress . I think now is about the time that you'll want to start honing in on what you want the deck to have a focus on; given the push for eldrazi and X spells, I think you could drop Brudiclad, Telchor Engineer and Thopter Engineer . I'd personally cut Reverse Engineer , Saheeli's Artistry , and Masterful Replication and start looking into more payoffs for Saheeli's +1. You may want to consider one or two of the following for casting on other people's turns to avoid as much trouble on your own turn: Shimmer Myr , Vedalken Orrery , and/or Leyline of Anticipation ; these will also play well into Unwinding Clock . I think Palladium Myr is droppable given if it doesn't have haste it's functionally a Worn Powerstone , and Pristine Talisman , Prismatic Lens , and Izzet Locket can be pretty underwhelming. Blue Sun's Zenith and Expansion / Explosion are draw spells that use Saheeli's ability as a payoff, and BSZ will shuffle back in. If you want more draw, Slate of Ancestry is good if you find yourself with a lot of creatures, Tower of Fortunes if you end up with a lot of extra mana to spend, and Loreseeker's Stone if you find yourself empty-handed most of the time.

Those are great swaps! Since talking to you, I've been thinking about my own Mizzix deck and I have some more suggestions.

Regarding Artifacts: I would talk out Brain in a Jar, Seal of the Guildpact, and yes, Sapphire Medallion. Instead, try looking for mana rocks that provide colored mana. Some good ideas are Springleaf Drum , Izzet Signet , and Izzet Locket . All of these provide faster, more reliable ramp, especially the signet and drum, since tapping Mizzix changes nothing about her effects.

Regarding Creatures: I've found Mizzix works best with lots of token generators. I see you have Talrand and Docent already, so here are two more similar cards: Young Pyromancer , and Murmuring Mystic . These will give you the blockers that Mizzix will never be.

Regarding specific spell swaps: I would look at Brass's Bounty , Expansion / Explosion , and Firemind's Foresight . Each of those can easily give you a huge boost, if not the game.

I almost feel like Narset's Reversal is going to be more versatile and relevant more often than Expansion / Explosion . You might already be running that though, I guess I'd need to see the deck to actually judge it.

How much sense does it make to include a split card in a list for only half of its effect? For example, putting Expansion / Explosion in a mono-blue deck just for the cheap 2-mana copy in Expansion

Just a heads up, you cant cast Jaya's Immolating Inferno unless you have your Kefnet the Mindful in play. Perhaps Expansion / Explosion could work better here? I like the deck though. Happy Brewing!

Just some straight upgrades I can see while keeping some budget in mind is

Divination out for Think Twice , Deep Analysis , or Frantic Search

Getting better triggers off Keranos you could swap some cards out for stuff that lets you scry during your upkeep like Eyes Everywhere or Galvanoth

Young Pyromancer could be a good add to make more tokens and it costs less to get out than your other token makers.

I've found in my own Izzet deck that mana ramp really needs to be a big part of your deck since you don't ramp easily. I use Curious Homunculus  Flip since he can tap for mana and flips into a prowess creature that reduces mana cost.

Tutors are always good to add and Long-Term Plans is a tutor in blue that will let you search for any card and not need to reveal it.

Expansion / Explosion is a good card since it will let you copy a spell or act as a big blow out spell if you have nothing else to do.

One card that I love that synergies with Thousand year storm is Baral's Expertise since if you get copies of it then you are bouncing tons of stuff back to people's hands and getting free casts into the storm.

Titus7007 Find out what your game plan is and go from there - what do you want the deck to do? Setting up for a combo finish with Niv-Mizzet, Parun or Thousand-Year Storm ? Drawing cards and adding synergy that way? A control deck with PW's as finishers? There are many ways to go, but cards like Runaway Steam-Kin , Goblin Electromancer , Faerie Vandal , Torbran, Thane of Red Fell and Niv-Mizzet can't go in just any deck and be good. Don't get me wrong, they can all be strong cards, but they need a deck that fits them. Electromancer you won't see much outside of Arclight Phoenix decks, but it's so good there that they don't play less than 4. Niv is a mainstay in the Temur Reclamation decks because the deck is set up to play a bunch of spells, draw a ton of cards and go off with Expansion / Explosion . Torbran slays in mono red because they have a ton of reach and pings etc.

Chemister's Insight is good in a deck that wants to keep their hand stacked while keeping mana up for counter magic (ex. control) or dig for a combo piece (ex. Temur Reclamation). Outside of that I agree with Sorin_Markov_1947.

Keep in mind that all x/2 creatures you add to your deck will make your Flame Sweep worse. That doesn't necessarily mean you should avoid them entirely, but it's worth considering when brewing.

TL;DR you have a bunch of strong cards, but lack a focused plan and therefore synergy.

As for Spark Double try and check out this Temur walkers deck https://www.youtube.com/watch?v=TjbpYMKiRAA

Thanks for the suggestion: I already have at least Expansion / Explosion , Increasing Vengeance and Reiterate immediately available, so I guess they can begin to go into the deck and see how it improves.
