Deekah, Fractal Theorist

Legendary Creature — Human Wizard

Magecraft — Whenever you cast or copy an instant or sorcery spell, create a 0/0 green and blue Fractal creature token. Put X +1/+1 counters on it, where X is that spell's converted mana cost/mana value.

: Target creature token can't be blocked this turn.

KongMing on Krark's Raging Storm

Disappearing Act gives you reliable evasion - even if the spell fails because Krark is on the field, the cost of the cast allows you to bounce a permanent to the safety of your hand.

Also, Reliquary Tower, so you don't get forced to discard down if you keep bouncing spells to hand.

Deekah, Fractal Theorist can grant you some token swarm, especially if you copy them with Sakashima.

You should really find room for God-Eternal Kefnet if you can, because their wording specifies you cast the copy. It's also a may effect, so it doesn't give away your draw unless you decide to cast it.

Very high CMC, but another fun target for Sakashima in this deck might be Jin-Gitaxias, Progress Tyrant.

Less-high CMC, a fun combo with Krark is Melek, Izzet Paragon. Even if you fail the coin flip when you cast a spell from the top of your library, you still get to 'draw' the card! Also potential Sakashima shenanigans.

Rootha, Mercurial Artist can help make casts a bit more reliable - if you're willing to bounce them to hand, you can copy a cast spell before Krark potentially bounces it back to hand.

Misconception on Zaxara, the Exemplary | X Gon' Give It to Ya

KongMing thanks again! I really like Deekah, Fractal Theorist but I'm note sure if Herald of Secret Streams isn't just strictly better... I will have to playtest that one! As for the other two, they just seem too slow even with all the X-spells being thrown around or even infinite mana generation... but I will keep them in mind in case another card ends up underperforming!

So Deekah, Fractal Theorist might be a good way to 'double up' on the big X spells you cast, and also gives you some unblockable for your big hydra tokens at instant speed.

Geometric Nexus falls into a similar vein.

Finally, Orochi Hatchery might make a good mana dump if you don't end up spending it.

Rhadamanthus on I need some clarity... strive, …

It wasn't clear exactly what you were asking until you brought up Deekah, Fractal Theorist as an example of why you needed to know. A card's "mana value" is specifically the sum of the mana symbols printed in the upper-right corner of a standard Magic frame. If there's an in the cost and the spell is currently on the stack, then the chosen value of X is counted as well. Nothing else that would increase, reduce, or otherwise change the total cost required to cast a spell has any effect on the mana value. The only way to change the mana value of a card is to turn it into a copy of another card with a different mana value.

Don't hate me... I just noticed every strive spell says "any number" as part of it's initial targeting, which is why it shouldn't be an additional effect or cost... it's a part of the original effect, the initial casting and targeting of the spell. Therefore the total spell cost, which has simply been modified and expanded, should include it. IMHO. This matters if, say, Deekah, Fractal Theorist is in play.

balefire123 on Tibor and Lumia Deathslingers

I like this! An uncommon Commander with some spice in the list. This seems the perfect deck for Student of Elements  Flip, and I don't think I've seen a better list for Mass Diminish and Polymorphist's Jest.

The easiest addition, imo, is Trinket Mage to fetch Basilisk Collar, Sol Ring, etc.

Cards like Archaeomancer and Ardent Elementalist aren't particularly exciting, but they do help by adding more recursion/redundancy to the deck. The Mirari Conjecture does something similar, but with an added bonus after two turns.

Enchantments like Dismiss into Dream and Cowardice are some spicy ways to turn blue cantrips into removal.

I think the token producers (especially Young Pyromancer) conflict with T&L's second ability, but I also think they offer up an opportunity for a new win condition: Dragonshift. If you go this route, I'd suggest adding cards like Murmuring Mystic, Talrand, Sky Summoner, Metallurgic Summonings and Shark Typhoon. Deekah, Fractal Theorist deserves special mention, as the tokens it creates will keep their +1/+1 counters even after being Dragonshifted.

I don't like Kaza, Roil Chaser here, because I see this as a deck that wants to be casting a bunch of small spells, not a few large or X spells. I also think you are leaning too heavily into copying spells for much the same reason. Copying a Brainstorm =/= copying a Comet Storm. Even copying Stitch in Time feels like a waste. Maybe take out cards like Increasing Vengeance for more counterspells or interaction? Archmage Emeritus, Niv-Mizzet, Parun and Wavebreak Hippocamp help you maintain card advantage even when countering your opponent's threats.

Overall, I feel this deck is looking to control the board with cards like Basilisk Collar or Mass Diminish + Tibor and Lumia, maintain card parity with counterspells + cantrips and Archmage Emeritus (and company), and then follow up with either a swarm of tokens + Dragonshift/Day of the Dragons or individual threats such as Niv-Mizzet or even Nezahal, Primal Tide or Hullbreaker Horror. I think you'd be best served by upping your interaction/counterspell suite, eliminating some of the more expensive sorceries (everything 4+ MV) and X-spells, and focusing less on spell copying in favor of casting more cheap spells in the first place. I hope this helps! I haven't really thought much about this commander before, so thanks for bringing it to my attention. Might try my own spin with this lovely Izzet couple.
