With current spoilerz:
With arid unmaking aymara will be used more as burst/healing than body
(At least against removal heavy faction like vanar)
I hope sister saon becomes viable eith the exp (vuv)
I fear the exp will leave the stronger decks where they are, and leave out already weaker ones
I hope for more new tile support than the cards they already spoiled
I hope circle of dessication will be buffed adding "every friendly minion will leave an exuming sands tile"
Oserix + arid unmaking + tears:
improbable, weak, fun.
Neutral blue boar can make viable astral phasing by himself
I can see lady locke working with the new tiles, i don't know if the effect procs and how many tiles will be summoned in an average game for her to be usable tho
Portal guardian, will it be good enough? My take is no. i'm thinking positive.
Venom toth will be a tech for vet if they become too problematic
Grailmaster will probably be a good budget wincon for vet players
Zurael tech for fun in sand tile focused decks, (against aoe and such)
Mirage master will be, in my opinion, a really good card
Duskweaver is a captivating name for a new brand of fridges, i like his effect, i think more than someone will play it
Just a tought dump.
