I'm going to go over the list of possible choices for the 5 sorcerors in the upcoming episode.
Wotan (likely)-his magic seems powerful enough, can break out of prison
Anton Arcane-kinda obscure, more of a Swamp Thing foe
Blackbriar Thorn-also obscure, seems interesting enough, druid
Circe-well known as a Wonder Woman villain, who said they will make the sorcerers all male
Deimos-obscure, Warlord villain
Effron the Sorcerer-obscure
La Enchantadora-obscure, female Superman villain
Enchantress-obscure, sometimes a superheroine
Felix Faust-likely to appear, already in three DC animated shows
Jinx-teen titans villain, should be portrayed as Indian if she appears
Ian Karkull-Dr. Fate villain, a possibility
Klarion-likely, though he's working with the light, do they want to rid the world of adults?
Mordru-a possiblity, though a Legion of Superheroes baddie, he appeared in JL cartoon
Morgaine Le Fey-possibility, though I rather not have her used since she was in a similar JL episode where Mordred got rid of adults
Neron-not sure about this guy
Queen of Fables-obscure
Tala-possibility, was in JLU
Warlock of Ys-a possibility since he's a Zatanna villain
Wizard-not sure about this, JSA villain, prolly deceased
The likeliest candidates to be the sorcerors, Wotan, Circe, Felix Faust, Jinx (it's young justice), Ian Karkull, Klarion, Mordru, Morgain Le Fey, Tala, and Warlock of Ys. Though I wish they use different characters than ones that appeared in shows before.
