I had decided to:
1. Save my units for 6.2;
2. Stop ranking 5* (I have duped 5* R5 Blade and Omega) and start focusing on 6* (have Hawkeye, King Grrot, Hela and Punisher 2099)
But then I got this guy!

And now I don't know what to do. Should I instead 100% Variant 2 to awake and R5 him? Should I use him unduped, since he has good synergy with Omega? Should I just ignore him and stick to the plan? Arghh...
