Hope it is ok to keep going with the Star Wars stuff even if not associated to Bad Batch.
I still think that Heir to the Empire #1 is grossly undervalued. Admiral Thrawn is already Canon, a fan favorite, cool character, and will continue to be utilized by Disney.
The other thing about Heir to the Empire #1 is that it also contains Mara Jade’s 1st. Her history may not be incorporated into future films, but you never know. She is also quite popular among Star Wars fans. I frequently see cosplayers dressed up as her. Along those lines, you can also get her Dark Horse mini-series on the cheap as well.
Heir to the Empire has risen steadily, but it is still quite inexpensive relatively speaking.
