Trying to catalogue all the pins that can be pulled from the Mystery Pins Booster available at the official merch store & all the Pin Program Sponsor options, since WotC hasn't published a nice graphic including all the info as they did for previous cons. 

Mystery options known so far, all from Lorwyn Eclipsed card art: 

\- Changeling Wayfinder

\- Grub, Storied Matriarch 

\- Crossroads Watcher

\- Ashling, Rekindled 

\- Disruptor of Currents 

In the past there's been 7 or 8 common pulls in the Mystery pack plus 2 chase options, for a total of 9 or 10 possibilities (sometimes 11 if there was a Pin Trading Booth which had one you could buy outright!). Unclear whether the same is the case this year, but if the pattern continues there are 4 or 5 more designs. Please comment if you've found any others! (pics much appreciated)

The list of Pin Program Sponsors, with pin name if known:

Cool Stuff Inc: Elesh Norn

Journey's End Games: Elspeth 

Strike Zone: ? 

Pink Bunny Games: ?

Stomping Grounds: ?

J.K. Entertainment: ?

Trans Lifeline: ? (official merch store has 2 🏳️‍⚧️ pins in partnership with them, but presumably their booth has one of the chibi art style pins for a card/character)

If you know which sponsor has Chandra, Urza or the Doubling Season goose please let us know so this can be updated for posterity! Photos of Elspeth or the other 2 sponsor pins would be amazing as well. 

Last pic is the Fblthp "Staff Exclusive" pin that can be traded for (best bet is the info desk). It was also given to every Black Lotus VIP badge holder. 

Known Pins: Mystery Merch, Sponsor, Staff/Black Lotus trading
