If Rip’s team may encounter known villains in the Past or Future, who do you think they will face and in what timeline?

I'm just saying since in episode 2 they encountered Damien Darhk so in their pursuit of Savage they might encounter villains from the past & future as well. Also here's my thoughts:

Morgaine le Fey-The Dark Ages
Blight-2058
Black Adam-Ancient Egypt
Klarion the Witch Boy-Salem 1780
Ra’s al Ghul-Anywhere in time
Jim Craddock/The Gentleman Ghost-1870 {Picture}
Cult of the Cobra-South America 1931
