There are a number of things going on in this Level-Up pool, so I'll start with the overall flavor I was going for when putting it together. I wanted to touch on the celestial themes of the art design, especially the connotations of protection ("guardian angel") and mysticism (a sense of "the unknown," as it were). Dante tells us that angels can be good or evil, and so I've thrown in a touch of both as they almost duel with one another as the Poke levels up, to make the flavor more complex. These elements not only reference the Psychic secondary-typing without being overt, they also play to the "pseudo-legendary" notion of our 600 BST stat spread by implying a greater backstory than meets the eye (not that I have a particular story in mind, but they should lead to plenty of good Pokedex entries). I also tried to experiment with text-blocking and visualization, wherein if you give the list of moves just a quick skim or passing overview, it should make four words jump out at you without you necessarily noticing: Dance, Wind, Heal, and Wish. That is because those words are all repeated more than once amongst the move names themselves and are often spatially situated either near each other (for impact) or far apart (for the reminder-effect). So, you should feel a subliminal sense of whimsy or lightness from those four words' connotations, even as you read through the list word-for-word. If it doesn't work, then oh well; it's a poetry thing, I'm not particularly familiar with it, and it's not super important.
Moving on, I use the Biblically-significant number "3" as the backbone for three consecutive sets of three moves each: Silver Wind / Sunny Day / Heal Pulse ; Ominous Wind / Will-o-Wisp / Final Gambit ; and Ancientpower / Wish / Healing Wish. The core of the movepool, these three sets all have similar progressions of [attack]-->[general aid]-->[specific aid]. The first set (presumably belonging to the "Basic" or "Baby" evolutionary stage) is much more innocent and subdued than the latter two, which focus on the more mature concepts of suffering (Will-o-Wisp to create suffering vs. Wish to remove suffering) and self-sacrifice (Final Gambit to hurt an enemy vs. Healing Wish to help a friend). The narrative of the learnset, based on this progression, is that while Aurumoth (or its pre-evolutions) can be robbed of its innocence and tempted with "evil" or aggression (@Ominous Wind/WoW/Gambit), as it grows and matures (evolves), it becomes more selfless and "good," in the end. I'm thinking if we go for a three-stage evolutionary process, we could choose any sort of method to flavorfully bring it all together, although I personally think activating evolutions at the learning of Ominous Wind and Ancientpower would be most acceptable in this case: the basic stage could be a cutemon, the middle stage emo or something, and the final stage, of course, would be Aurumoth itself (there are even precedents for evolution-by-Ancientpower, including Yanma-->Yanmega). Speaking of Biblical numerology, although less significantly, I also use a lot of the Biblically-significant number "7" in the Level-Up pool: attacks begin to be learned at L7, all attacking moves are learned at a level with a singles digit of "7", and most moves are learned seven levels apart, excepting Ominous Wind, Ancientpower, and Tail Glow, the three of which are learned six levels after their previous moves, for a touch of subliminal mystery (6-6-6 wtf!?). There are also 12 non-Heart Scale moves to be learned, and 12 is a major Biblical number as well.
The movepool as a whole is largely pacifistic, which I thought was appropriate for a seraphim design, and so the only attacks included here are Tackle (out of necessity for a generic starting attack), and then Silver Wind, Ominous Wind, and Ancientpower. I like these moves not only because of their individual flavor merits (irrespective of one another), but also because they are the three moves available that each have a 10% chance of raising all of Aurumoth's stats at once, but with only 5 PP apiece, which is my sort of tongue-in-cheek allusion to the concept, flavor-wise. Ironically, Aurumoth gets all of its best stat-boosting moves here as well, either by leveling up to Tail Glow or by going to the Move Relearner with a Heart Scale or two to unlock the secret Dancing powers it never knew it had.
Aurumoth gets three recovery moves here: Heal Pulse, Wish, and Healing Wish, and while it can only benefit directly from one (and even then it doesn't necessarily benefit), the moves still offer that "guardian angel" vibe of taking care of its teammates, even if it's at a cost to Aurumoth itself. Other flavor choices include Sunny Day and Will-o-Wisp, which I added because of the angelic connection to fire and flame (Seraph literally means "burning ones"). In the case of these moves, Sunny Day represents more of the "clarity" aspect of the angel-fire relationship ("Clear Sky" is the Japanese translation of the move, and Sunny Day itself is a Fire-type move), while Will-o-Wisp offers the more literal interpretation of "creating fire."
