2.1. Mythics

There are two Sagas here. Both are black, costs 6 mana for 3 chapters, just with a toggle for whether to add green and to separate the last two chapters. Other pairs here are two normal creatures in White and Colorless and two big event sorceries in Blue and Red.

Speaking about Izzet, there’s also a normal creature of them too, a <Direction> Wind Avatar, normal creatures across rarities that collectively cover 5 colors by 4 cards, which left this mythic one to be the only multicolored one. Well, why isn’t there a Center Wind Avatar to offload the color to? Suddenly, the Kodamas in Kamigawa felt really cohesive.

With that, we managed color imbalance for mono blue, against mono green, Boros and Simic. Do I have a solution? I would say put the gecko in green, the keyword robot to Boros and the construct to Simic, because it says right here draw and counter.

2.2. Rares

There’s a cycle of Classes here. The white one might make you think that we’re repeating the Bloomburrow name structure. But the others have other plans. The first two levels start at 2 mana 1 devotion except three cases, a fourth if you count the red one’s third level. Art wise, the black one depicts a human instead of a turtle and for that has a distinctly different artstyle than the rest.

What else is there? You can find the most normal creatures in white and also a Fact or Fiction version of mass wishing. Black has another creature for that life gain loss loop. Red has two artifacts asking for a single red for their activations. Lastly, green has two cards with just two lines of text each.

Colors balance wise, Izzet got the short end of the stick. Can I pick some colorless cards up to make them feel happier? Red has a Manalith that have the last mode be Lightning Bolt, that feels prime for red. Actually, there’s a robot that creates blitz copies of stuffs too, that sounds red too. Blue feels like a hard case, with the other artifacts caring about delve for Mutagen, buffing the titular kindreds, or vaulting creatures for a faithful day.

2.3. Uncommons

Once again, there are three enemy cycles. Two are commanders we’ve already seen, the last one are five magecrafts. Only the Golgari one is an instant, only the Simic one can’t remove a creature, the other three are all entwined modals, so they don’t have any flavor text.

Monocolored wise, there’s a cycle of Equipments that ranges from giving double strike and nothing to being snap on in Golgari, wanting to be snapped on in White, tapping in colorless and bouncing in blue (with a letter you can’t type from the English keyboard in the name).

Each non-red color has two normal creatures, except blue traded one for a colorless that acts a lot like a white card should. Lastly, there are some removal staples: Ossification, Eliminate, Overprotect and lastly, a burn spell turned into a pizza that you pay life for.

Colorless wise, we got two cards explicitly calling Turtle and a pizza that have a 5 colors mana sink instead of the typical 2 mana to gain 3 life.

2.4. Commons

There are two enemy cycles of creatures: One costing 1 devotion and is the enabler, and the other costing 2 and is the payoff. Izzet has both cards being artifacts, while the other ones are Golgari and Boros. Both Orzhov cards are Human Ninjas and all four green cards are Mutants with only one of them not having a third creature type.

Monocolored wise, let’s look at how some bones (set skeleton staples) got twisted:
