My ideal starter JSA post-Future State. (Note these are characters I feel make the most sense, not who I would prefer):

Alan Scott
Jay Garrick
Hawkman
Atom Smasher
Cyclone
dr Fate
Hourman Rick
Dr Midnight Beth
Wildcat Yolanda
Jade
Obsidian
Stargirl
Mr Terrific Holt
Jesse Quick

Possibly Jakeem later on
Possibly Powergirl later on

I didn’t even put my favorite Ted Grant on, because I realize Yolanda deserves a second shot.
