Morimens 2.5th anniversary has arrived with a ton of updates, including a rerun banner for every arc 2 awakener! You can also get a free copy of any previously released arc 2 character by using Posse 200 times. If you've been wondering who to pull for/selector, this guide will briefly analyze each option.
Doll: Inferno (GDoll) - GDoll is a powerful support and Poison DPS with team wide Aliemus generation through her Exalt, healing through her Rouse and 3 cost, and the choice between either DMG Amp or STR reduction for 1 turn on her 2 cost. GDoll is rather infamous in the community due to the massive improvements her dupes provide, to the point that there are people who will tell you GDoll is an "OE or bust" character. There is truth to this, but she's still usable at lower dupes. She's completely fine at E0, providing a good amount of healing every turn and can reliably Exalt every 2-3 turns. Pair her with an Aliemus battery like Winkle, Miryam, or Thais, and you'll get consistent Exalt spam off between the two of them (and the rest of your team). E2 makes her significantly more self sufficient, and when paired with the previously listed awakeners, allows her to consistently Exalt every turn/other turn. With that said, you should plan on eventually reaching OE, as it IS a significant improvement. The other issue is her wheel choices; she REALLY wants wheels that have a "wielder's Aliemus gained increased by X%", which are typically (exclusively?) found on SSRs. The most accessible of these is Winkle's wheel, but the other options are limited wheels. Because of the sheer amount of investment required for her to truly reach her full potential (especially if you plan on using her on Poison teams), I consider her to be LOW PRIORITY despite how strong I personally consider her. If you ARE willing to invest pulls or many shop dupes though, she's one of the best characters in the game and a mainstay for many teams across all content.
Playable: E0
Good: E2
Ideal: OE
Clementine - Strangely overhated character. Clementine is considered extremely strong in CN but mediocre in Global. I lean more towards the middle here. On one hand, Clementine is a consistent STR scaler and Keyflare generator who doesn't NEED to use her Quasar (Leap) effect each turn since her Rouse only cares about the first Clementine card played each turn rather than it being the first card played (provided you don't mind losing on the STR). On the other hand, Clementine feels slow and awkward without E3 as she is otherwise reliant on dealing damage to build up her passive stack (albeit not as slow as Kathigu-Ra). I think that if you are willing to invest in the long term, especially towards OE, Clementine is a very powerful support who exemplifies the power creep of arc 2 supports by actually dealing decent damage on top of her supportive capabilities. She also synergizes very well with STR hyperscalers like Kathigu-Ra or Doresain, provided you want to realm mix with Ultra on the team. Overall, I consider her to be LOW-MID PRIORITY for the average player, but if you're a fan of Ultra OR want a good support she's a fine option.

Good: E3
Ideal: OE
Corposant - Corposant is a flexible awakener who can do a bit of everything. While the main idea is to use her in Aftershock (discard) teams, she's a general purpose support that provides a decent amount of STR/tentacle scaling or shielding while scaling with Death Resistance for riskier strategies. Her damage output is very high for a character that reads more like a support, and she has lots of on demand survivability thanks to the cards she creates. Her Exalt lets you both remove a bricked hand on demand and draw the same amount, a utility that is very rare in this game. With dupes, she can even apply Weakness (E2, on her 2 cost [Ominous Semaphore]) and Vulnerable (E3, Exalt) for some more utility. Her only real flaw is that Aequor lacks a particularly good carry in house, especially one that actually scales with Tentacle DMG (sorry Tulu), and that Aftershock is only "OK" as a team at the moment. I consider her to be MID PRIORITY, or lower if you don't believe or want to wait for a good Aequor DPS. Her value increases greatly if you happen to own and want to use a well invested Tulu and/or Aurita though.

Good: E1-E3
Ideal: E3/OE
Doresain - Doresain is a Caro DPS who is all about nuking singular enemies with high base damage and even higher STR scaling. I'll admit that I'm completely biased as I'm a fan of Caro. Post buff Doresain is the CHEAPEST character in arc 2; E0 is already good enough to do his job of nuking life bars. His only real flaw is when enemies with low enough health to divert his attacks but high enough health to not die easily to his attacks show up during a boss battle. Otherwise, Doresain is one of the best single target DPS in the game, whose dupes only make stronger. Since his cards are mostly superfluous outside of giving him Aliemus or some decent utility (1 turn Vuln from his [Netherward Path] card or STR scaling from his expensive [Dirge of the Fallen] card) he's also very action generous, which is particularly good in arc 2 due to its infinite prevention mechanic. He's also significantly less risky than the other Caro DPS, as unlike them, he has very little self damage and has built in healing through his passive. While dupes do greatly improve both his speed and damage output, they're not needed to do his job; a blessing in the fairly expensive feeling arc 2. Overall, I consider him to be MID-HIGH PRIORITY due to his strong performance at low dupes and relatively easy gameplay.
Playable: E0
Good: E0-E3
Ideal: E3/OE
Kathigu-Ra - Kathigu-Ra is a Chaos DPS who can deal utterly ludicrous AOE damage with enough investment. Her damage has dual hyperscaling in the form of both STR scaling and her own passive Combust stacks. As a Chaos character, she has great flexibility with other realms and can pair with all sorts of awakaners, including oft-maligned ones like Cassiah. I've seen people say she NEEDS E3, which I can't really agree with. She definitely WANTS E3, but the arguments typically feel like people saying GDoll NEEDS OE. Like most arc 2 characters, Kathigu-Ra's dupes are all about increasing the speed of her kit and the damage she deals. Personally, I'd say E1 is a strong and cheap QOL starting point, E3 is a competitive (and community consensus mandatory) investment level, and OE if you want to trivialize content. Overall, I consider her to be LOW-MID PRIORITY since most people reading this likely favor convenience; and at lower dupes, she's not. If you're willing to invest dupes into her via shop dupe/rerun banner then you can bump this to HIGH PRIORITY though.
Playable: E1
Good: E3

Pickman - Pickman is a Caro support who deals a surprisingly high amount of AOE damage as a support and has a unique gimmick through his creation of Command Cards with Orisons attached or 1 turn Silver/Gold relics. Pickman was a long awaited Caro support to alleviate pressure on using Thais on every team. He somewhat accomplishes this (although Thais remains the Embryo Fusion queen). Pickman's Embryo Fusion is certainly slower than Thais' E3 passive 50% Embryo Fusion every turn, but he makes up for it a lot of other ways. Notably, Pickman's 4 cost [Chromaphage] (which typically plays for 2 thanks to its cost reducing every time you Discover (picking an option from a selection, although not everything that does this counts)) deals very high AOE damage and steals STR from the enemy. You can stack multiple of these in hand via his Exalt, which lets you pick from 1 of 3 Command Cards to create and add to hand, allowing you to neutralize an entire turn all while setting up your own nuke. Whereas Thais gets most of her esoteric value from creating copies of a Command Card, Pickman gives you a more straightforward Exalt focused buff. But if you want eccentricity, Pickman is the only character in the game currently who can let you add random relics for a turn, based on classic generic or Caro related relics you can find in arc 1 exploration. The Command Cards he makes are also different from Thais; whereas Thais copies any realm related Awakener card for herself, Pickman creates a copy of that card for the Awakener on your team. The Command Card also has a random Orison attached, although the Orison is unlikely to sway you in any particular direction. Pickman's dupes are mostly superfluous; E1 and E2 are OK, but the real star is E3 letting him potentially Exalt twice in a turn (or more realistically, lets him set up another Exalt on the following turn). Overall, I consider Pickman to be LOW-MID PRIORITY. He does his job well enough, and he's cheap compared to most of the awakeners in arc 2, but most of the characters that best utilize him are either arc 2 and/or are high investment awakeners. He also has stiff competition via Thais, especially if you've duped her to E3. If you have and use Doresain a lot, his value is greatly increased as Pickman was very clearly designed to be Doresain's direct support.
