It's probably both a blessing and a curse that half of Unfinity is going to be centered around Sticker cards. On one hand, it seems like a fun mechanic, though absolutely terrible for a structured cube format. There isn't a good solution to including the sticker sheets, and re-using the stickers over the course of multiple drafts. Supposedly, they use a post-it style sticking, which should make them semi-reusable, but that will wear out over time. Also, in order to make the stickers function, it requires a deep investment in cards that produce the tickets (read: energy 2.0), to make that draft archetype work. There's already enough competition for archetypes that I feel fine saying it won't go in.

The silver lining is that it means a significant portion of Unfinity is now off the table for inclusion in the cube, which makes updates and decision making easier.

From the cards that have been revealed so far in Maro's SDCC 2022 show:

Far Out: This one is sick, definitely want to find a place for it. You can pull off some amazing tricks with Seek Bolas's Counsel and Growth Charm. I might need to identify some more modal support, but I'll have to see what Unfinity offers for that.

Magar of the Magic Strings: Definite inclusion, probably replacing something like Keldon Twilight. Making a B/R spellslinger archetype that runs back Summon the Pack? Yes please.
