Brinelin, the Moon Kraken6UUG Legendary Creature — Kraken {MR}
Gorge (You may cast this card by destroying a creature and paying the difference in mana costs between this and the destroyed creature. Mana cost includes color.)
When Brinelin, the Moon Kraken enters the battlefield, if it gorged a creature, that creature's controller may search their library for up to two land cards and put them onto the battlefield tapped, then shuffle their library.
At the beginning of combat each turn, you may let nonbasic lands become 2/2 Elemental creatures that are still lands until end of turn.
5/8
Sidereal Sedation3U Enchantment — Aura {UC}
Enchant creature Constellation — Whenever Sidereal Sedation or another enchantment enters the battlefield under your control, you may attach Sidereal Sedation to target creature and tap it.
Enchanted creature doesn’t untap during its controller’s untap step.
Powered Tome3
Artifact (u) 1, T, Discard a card: Draw a card.
Whenever you discard a card, you may pay and sacrifice Powered Tome. If you do, return the discarded card from your graveyard to your hand. The first attempts at exchanging knowledge though electricity were not so unsuccessful.
Design .:. (1/3) Appeal: This is a fine Jxnny card. (3/3) Elegance: The card is easy to understand and makes sense.
Development .:. (2,5/3) Viability: Tomes are uncommon nowadays, that's fine. Returning a discared card to hand, has so far appeared one red card from 16 years ago, Pitchstone Wall. The only other comparable and much more recently card is black, Shadow of the Grave. Besides the wall there's actually no red card with an effect that returns other things than instant, sorcery, or artifact cards. Blue on the other hand has Monastery Loremaster for any noncreature, nonland card and Sacred Excavation, the more interesting card for this case. Cycling and discarding where treated very similar on Amonkhet. Blue being able to retrieve a single discarded card might be okey, a bend at worst. For red though I can't find any such examples. There's Codex Shredder of course that, like a lot of artifact, gives an effect to any color, but at a much higher cost as usual. Overall it's probably some kind of justifiable bend. (3/3) Balance: A different take on Urza's Tome and other books that works well with Izzet's mechanic jump-start while not appearing all too powerful.
Creativity .:. (2/3) Uniqueness: We know tomes in all variations. This izzet tome has quite the nice cover though. (3/3) Flavor: The flavor text reads like it's hinting at something. Like, "you would have thought the experiments failed, but! . . ." Intriguing.
Polish .:. (2,5/3) Quality: "Though" in the flavor text probably supposed to be "through". (2/2) Main Challenge: Main challenge satisfied! (2/2) Subchallenges: Both subchallenges satisfied!

Sneakbug Gadget1
Artifact (U)
When Sneakbug Gadget enters the battlefield, look at the top five cards of target opponent's library. UB: Sneakbug Gadget becomes a 1/1 Insect Construct artifact creature with flying and deathtouch until end of turn. Whenever it deals combat damage to a player this turn, you may put the top card of that player's library into their graveyard.
Design .:. (1/3) Appeal: This might be a Jxnny card. (3/3) Elegance: The card is easy to understand and makes sense.
Development .:. (3/3) Viability: Fine for a dimir card. (3/3) Balance: It seems weird to me that so far there's no card that just allows you to look at the opponent's top cards this way without manipulating them. It gives you some idea of things to come but probably is just not very powerful. The ability to pitch single cards away if you turn this into a creature is neat but also not too powerful. After playing this opponent will draw at least one of the cards seen before you can attack with the little bug.
Creativity .:. (2,5/3) Uniqueness: As said, no cards looks at the opponent's deck this way. Artifacts that turn into creatures we know. (3/3) Flavor: That's quite the flavorful dimir device. I like how the effects give you an impression of how this gadget is used.

Steam Engine3
Artifact {R}
Whenever you cast a blue instant or sorcery spell, put a water counter on Steam Engine.
Whenever you cast a red instant or sorcery spell, put a fire counter on Steam Engine. UR, remove X fire counters and X water counters from Steam Engine: Steam Engine deals X damage to any target. Goblin engineering at it's finest.
Design .:. (1/3) Appeal: This is a Jxnny card. (3/3) Elegance: The card is easy to understand and makes sense.
Development .:. (3/3) Viability: Fine for an izzet card. (3/3) Balance:Firemind's Research is a thing and probably just the better card in most ways. With the Research you need 5 spells to do five damage. With the Engine you'd anything between 5 two colored or 10 mono colored spells to deal the same amount. The ability to make 1 damage after 1 two colored or 2 mono colored spells, and 2, 3, 4 damage respectively, differentias this artifact fomr the enchantment. I see no balance issue with the Steam Engine's added flexibility.
Creativity .:. (0/3) Uniqueness: With Firemind's Research in the exact set where the Steam Engine is supposed to come from I can't speak of uniqueness. (3/3) Flavor: Then again, turning water into steam under the influence of fire is translated perfectly into card form here.
Polish .:. (2/3) Quality: "Remove" in the activation cost must be capitalized, e.g. Academy Elite. "It's in the flavor text should be "its". (2/2) Main Challenge: Main challenge satisfied! (2/2) Subchallenges: Both subchallenges satisfied!

Izzet Gauntlets2
Artifact - Equipment (Rare) U: Untap equipped creature. R: Equipped creature gains haste until end of turn. UR: Copy target instant or sorcery spell that targets equipped creature. You may choose another target creature for the copy.
Equip 2
Design .:. (1/3) Appeal: Untapping and copying, buzzwords that make Jxnny listen. (3/3) Elegance: The card is easy to understand and makes sense.
Development .:. (3/3) Viability: Fine for an izzet card. (3/3) Balance: This is a flexible combo piece that helps to abuse tap abilities and spells. The untap ability has appeared on an equipment once, see Sword of the Paruns. Whereas on an enchantment like Freed from the Real the untapping can be cheaply costed on an artifact that you can use again and again on other creatures the cost might be too cheap. The haste part on the other hand seems fine, almost expensive. Copying spells cost two mana if the source of the copy is itself an instant or sorcery. There's no direct comparison for this repeatable effect but with the added restriction it should be fine. Overall we have a very flexible card where each single effect is costed somewhat reasonable. If this wasn't tied to this equipment being attached to something I'd say this needs to be more expensive. The need for a creature might balance this all.
Creativity .:. (2/3) Uniqueness: An amalgamation of several known things. To highlight is that Beamsplitter Mage feels very similar to this while being from the exact set this card is supposed to stem from. (2,5/3) Flavor: The flavor checks out but I'd like a little bit more than just a name. The chosen abilities don't seem to tell a particular story.
Polish .:. (2,5/3) Quality: Usually it's "You may choose new targets for the copy." There is a mechanical difference here in that a copy of Assassin's Trophy (and a number of other cards and similar cases), usually able to hit any permanent, would only be able to hit creatures. Questionable if this interaction is worth it to introduce a never before used wording. As there's no card with a similar wording I can't say for sure if this is technically incorrect or not. If not this would be a viability issue with the same amount of deducted points. (2/2) Main Challenge: Main challenge satisfied! (2/2) Subchallenges: Both subchallenges satisfied!
Union of Flesh and Spirit3W Legendary Sorcery {R} (You may cast a legendary sorcery only if you control a legendary creature or planeswalker.)

For the rest of the main game, rolling the planar die costs 1 less to roll for each time it was rolled that turn for each player who did win the subgame. (Then planeswalk away from this phenomenon.)
