I literally asked to not do more than one of each so we could keep the discussion going longer.
>Sigh<
I apologize I misread that part.
Re :Elspeth
I see her "dying", either self sacrifice or imo most likely I see her willing going with Calix back to the Theros underworld after the Pyrexia war. We just have the story summary but the ending of Godsend and the summary made it seem like Elspeth only left the underworld due to Ashiok and possibly Phyrexia spreading. Once Phyrexia (for the present or the future) is gone I see her returning seeing her work as done.
Re:Kasmina
I think the Kasmina and twins stuff (and possible Ikoira) are tied to New Phyrexia, otherwise they kinda seem like they setting up another story arc which don't sure they do anymore. Per Maro Kasmina was gonna feature in Eldraine as a merlin like character which seemed to have been recycled for Strixhaven so it seem creative has something planned they wanting to so with her and the twins.
Darker twist is she really working for Phyrexia and is helping gather powerful pw to let them experiment on.
RE: Jaya
I mean, I think there is room if they split up what Chandra can do, like give Jaya the instant and sorcery side and chandra more pure damage, maybe Jaya gets impulse draw to reflect she's more knowable and give Chandra more of the elemental making. Just seems like they haven't and both seem like they'd fight for space.
I agree with the Jaya being there for old lore fans and likely keeping her and Teferi safe or at least not getting completed and having a heroic sacrifice.
RE: Saheeli
I do like the idea of her being a counter to Tezzeret.
RE: Narset
Her thing is also being a monk and being three-colored. We didn't see much of it outside of Tarkir but I do like,similar with Will and Yanling, she is a more physical blue centered planeswalker.
UNLIKELY
Garruk
Similar to Elspeth, seems a huge waste to have a whole arc to restore him after years of being cursed. More likely I see his story having to put his grudge aside to work with Liliana.
