Quick Draw Upgrade - Improving the Precon Commander Deck with $100 

Jace reawakened can’t be cast during YOUR first second or third turn. You can flash him in on anyone else’s beginning turns no problem if you’ve got the setup

Since it might be a bit constrained on the 100 budget maybe you can try 'Stella does CEDH' for the 300 upgrade: its usually not enough to get a lot of fast mana so it won't be a turn 2-3 combo win but it can still be decent control/mid range that still combos a few turns in without having to blow out into the thousands to get all of the fast mana stuff in.

I've got Ojer Axonil, The Locust God, Sorcerer Class, and Thousand Year Storm in it. Ojer Axonil makes all noncombat damage become a minimum of 4. Sorcerer class makes it so your creatures can tap for either red or blue mana, and also deals at least 1 damage to each opponent each time you play an instant of sorcery. The Locust god makes tokens every time you draw a card. With all the card draw, and Niv Mizzet, I feel like it'll be good. Thousand year storm is in it for obvious reasons. I also have twisted fealty and involuntary employment. Twisted fealty will win you the game through infinite combo, and involuntary employment allows you to create infinite treasure tokens through the same way. I also have cards like Rhystic Study, Mana drain, Mana Geyser, Birgi, and Cyclonic Rift. Also, Labratory Maniac so you can win if you deck yourself out. My strategy is to deal a lot of noncombat damage, make a lot of tokens, cast a lot of spells, and if all else fails, I can win by decking myself out. I'm not entirely sure how well it'll work in play, but I feel it's a decent strategy.

You actually have a way to make semi-infinite mana in the deck now. If you have Storm-kiln artist out and your commander out, then you cast cerulean mists as your third spell that turn, you can copy that spell basically for each card you have in your deck and create treasure each time. If you have Veyran out, you’ll create 2 treasures each time.

Can't wait for the $300 decklist!!

Twisted feality goes infinite, and so does cerulean wisps to dig for feality or any other answer you need, as long as you cast 2 spells before those 2 cards and you can swap what you are copying half way through if you hit

Add Ral, Storm Conduit, Grapeshot, Brain Freeze, Fork, Reverberate, Isochron Scepter, Dramatic Reversal, Thousand Year Storm and Aetherflux Reservoir. Gives you tons of wincons, more flexibility. That’s where I’d start. Then slowly add Jeska’s Will, Cyclonic Rift, Rhystic Study and the rest of the Izzet staples and Counters/Control Magic as budget allows. Not sure what this puts me at for baseline cost upgrade, but I don’t think it’s a ton.

The only note i would make on the cuts is elemental eruption. Youve presented the infinite card draw with cerulean wisps so if you grab storm kiln artist and make infinite treasures you can use the mana from the treasures to swing with flyers. Just another win con thats all it is true its alot of mana but early game its great to pitch it to faithless looting or ledger shredder

There are 96 arcane spells. One of those is Psychic Puppetry. That one card makes any arcane spell go infinite with Stella. Toils of Night And Day makes infinite mana by itself. Splice glacial ray onto it for infinite burn. Splice psychic puppetry onto Lava Spike for infinite burn. Gaze of adamaro? Assuming opponent has cards in hand, infinite burn. Swirling embers? You have psychic puppetry in hand. Infinite burn. Ire of kaminari? Infinite burn. Eye to nowhere? Infinte bounce. Splice puppetry and glacial ray and it's infinite burn too. Splice onto arcane is BUSTED with Stella.

Deck upgrade is missing a lot of cool cheap things you can do as most of the budget was spent on one land, a tutor and 2 mana producers. There are many creature buffs or burn cards you can add for $1 to give the deck some more focus. A lot have already been mentioned in the comments by others but an interesting one I'll be expierementing with is song of totentanz to give haste to all the tokens and Elemental eruption becomes a win condition with enough mana and draw looping. Many fun ways to build if you replace 20% of the deck, this upgrade kinda left it the same only changing 11 cards and not adding the pay offs it desperately needs.

I threw in melek reforged researcher cause its just a big body even a couple turns into the game. The first spell discount is good too.

Why is Thousand-Year Storm not in this deck? I would assume cost, but the payout of giving Storm to everything you cast would outweigh that?

So how does this deck win? Is it a combo deck or is it a what?

What is a libarry?

Like to see a $300 upgrade or a first $500 upgrade

As foretold in my opinion is way better than mindsplicer...

Why are the two people speaking if one of them is just going to affirm literally everything the first guy says? Like can we have some real conversation?

You have arguably made this deck worse

I hope they ban Stella
