Design
(2/3) Appeal - It has a good baseline for Timmy and opens enough space for Johnny. Spike isn't interested.
(1/3) Elegance - 10 lines of text on the front face is pushing the limits. Abilities returning auras, including Auras controlled by other players also add lot of clunkiness. Another problem is a last planeswalker ability where you choose target permanent and then any number of target modified permanents - honestly, its last part feels better without targeting, especially considering the fact you can't untap a permanent you modified this way because it wasn't modified on step of choosing targets. Technically, it's possible, but not very elegant or simple.
Development
(3/3) Viability - It's probably okay, but has only one minor issue of adding another color on the back side despite not needing said color (green). Not going to deduce poits for it, just feels slightly odd.
(2/3) Balance - I'd say ths card is rather safe, its front face is playable, it's back face is so-so. Ult is also not very exciting, and I believe copying ability can easily be cheaper.
Creativity
(2/3) Uniqueness -- Transform conditions and transform are quite unique, other than that, it's just known Estrid with enchantress powers.
(2,5/3) Flavor -- No problems here, although totem armor, indestructible and preventing all damage put together feelslike an overkill. We got it, thanks!
Polish
(2/3) Quality - "Transforms" instead of "becomes a copy" is a big issue considering it's a double faced card, where it violates not only readability, but a functionality of a card.

Design
(1,5/3) Appeal - Johnny may be interested in this card, Spike and Timmy aren't excited about it.
(3/3) Elegance - Despite having lots of mistakes (see Quality), this card's is pretty straightforward and understandable at what it does.
Development
(3/3) Viability - This card is perfectly blue indeed and rarity is okay.
(2/3) Balance - Despite having a nice static ability on the back face, this card rather belongs to a safe side. Big setup to flip it and very mild activated abilities that, again, need setup. It can be quite annoying in a right deck, sure, but far from being a big threat.
Creativity
(2,5/3) Uniqueness - that's a bunch if known effects printed before and slapped tigether but in rather interesting way. I personally like the transform condition.
(2,5/3) Flavor - The flavor of Mu Yanling's transformation is open to interpretation, and the card doesn't give a clue what ignited her spark. The names are quite generic, but that goes in line with other walkers from Origins set. Other than that, no problems.
Polish
(0/3) Quality - Lots of mistakes here. "Whenever you cast a noncreature spell,", dot after "Untap Yanling", missing dot after "Dowser" at the end of sentence. Missing "Then" in the second part of transform ability. "0 power" instead of correct "power 0". "You control with flying", "nonflying", "owners hands", "six target creatures loses".

Design
(3/3) Appeal - I believe all three sorts of players would like to play this card.
(2/3) Elegance - The fact it returns with a -1/-1 counter and gets exiled and transformed immediately makes little sense. I would rather make it its own ability.
Development
(3/3) Viability - No problems here.
(2,5 /3) Balance - It seems like a perfectly pushed card, like planeswalker version of Chewill - it kills, it returns, it kills again and can draw you cards. Very strong, considering the fact it also has easiest flip condition, like Liliana, Heretical Healer.
Creativity
(2,5/3) Uniqueness - A planeswalker that flips after being killed earns high score. Loyalty gaining ability and Azorius hate are quite unique too, other less so.
(2,5/3) Flavor - It's good you didn't make her creature part an Assassin. But one minor issue - this flavor text belongs to her late, planeswalker version.
Polish
(1/3) Quality - Reminder text isn't italicized. Flavor text isn't italicized. "Returned to the battlefield from the graveyard" is likely wrong too, I guess wgat you wanted is "When ~ enters the battlefield, if she entered from a graveyard". "Blue or white" order must be reversed.
(2/2) Main Challenge (*) - Met.

Design
(3/3) Appeal - Timmy likes to have fun with dragons, Johnny knows ways to break it, Spike would love to play a 3/1 first striker with upsides.
(1,5/3) Elegance - Many parts of this card would look better if worded differently. The first confusing part is " If you do, exile him, then return him to the battlefield transformed under his owner's control." It reads like ut belongs to a dragon, not to Sarkhan. Okay, I remove the bit about indestructible and such which belongs to actial card (although the card existing doesn't make it 100% elegant by default), but the point about a creature still having loyalty sbilities stands since you insisted that it copies an ability from Dragonspeaker that makes him a creature but doesn't keep him a walker. The last inelegant part is "Dragon with exalted". It has some corner cases, but mostly works for a dragon you granted exalted to, and that dragon is likely not going to be a Sarkhan himself.
Development
(2/3) Viability - Exalted can be red, although it's rare, but hexproof isn't. You better go for some sort of ward that punishes the opponent, this I much more prominent among red cards.
(2/3) Balance - It's baseline is pushed to the limits and more. I believe it would have been much more better as an aggressive creature that either attacks each combat if able, can't block or has first strike only when attacks. Or maybe it should hare mana cost at least rr?.. The planeswalker part just adds more.
Creativity
(2/3) Uniqueness - Oh, I forgot to give an explanation last time. Different versions if Sarkhan have different abilities of turning to dragons, but this time you used the exact, and quite specific ability of existing one. Other than that, abilities are unique just enough.
(2,5/3) Flavor - Despite mtg wiki calling Sarkhan a "soldier", when it comes to actual card, I think you must go for Warrior or Shaman, both, unlike soldiers, make much more sense for Mardu horde.
Polish
(1/3) Quality - Quite a lot of mistakes. First strike shouldn't be capitalized. Dragons "have" abilities due to the static ability if Sarkhan, not "gain" them. The entire "becomes a dragon" ability is worded improperly, see also Elegance section. If you wanted it to become a legendary dragon, it must have a name, or better it would be a dragon in addition to its other types and have "that's still a planeswalker".
(2/2) Main Challenge (*) - Met.
(2/2) Subchallenges - Both met.

Design
(2,5/3) Appeal - Timmy may be fascinated by the numbers. Johnny sees ways to break this in half. Spike must be less excited, but only a bit less and still sees a super solid 1 drop.
(1,5/3) Elegance - It's not like it worded improperly, but there is a way to make the first ability if a front face more readable. But the real issue is the second ability of its back face. Until now, most such abilities were "0:" abilities, know why? Because it would immediately raise questions of what the number of counters is? A number before activation or the number after? And even if this question has an answer (and precedent, see phyrexian Nissa), it may be a headache for less experienced players.
Development
(3/3) Viability - It's quite fascinating how a hybrid planeswalker can be done properly.
(2,5/3) Balance - It's a pushed card, because it doss quite a lot for a 1-drop and with right setup, it can land its quite devastating ult on the same turn you cast it, which is not something we see often. Usually, walkers leave some room for opponents to react. But the setup is still needed, it just can be done without Grist itself...
Creativity
(2,5/3) Uniqueness - Except for removal ability, everything about this card feels fresh. Although mass token producing ults were done before too.
(3/3) Flavor - We don't know the actual circumstances of Grist's ignition, but you captured the flavor of the insect queen gaining enough subjects and becoming a sentient, planeswalkung embodiment of an insectile swarm perfectly. Good job.
Polish
(2,5/3) Quality - You use both "her" and "it" on the same card, better settle for one option. Other than this, no problems, I mentioned clunkiness of an ability in the Elegance section, but the formal quality is alright.
