The current ISA from Stargirl:
Icicle
Brainwave
The Gambler
The Fiddler
Sportsmaster
Tigress
Solomon Grundy
vs.
Stargirl, Hourman, Captain Midnight, Wildcat, Stripe
Plus through the dimensions they get
Ollie, Flash, Batgirl, The Legends as currently constituted.
I'm not crossing over Supergirl, Superman or J'onn as that would be a monumental stomp.
Recall the ISA seems to have taken out a Flash, GL and Dr. Fate.
