Ehhhh... not really. Rogue at best, but even then that's pushing it cus they need to open decent to do something. Also worth noting they brick even worse than Blue Eyes or Ancient Gears
Plenty of people have reached King of Game rank with Cyberdark and have shared their decks here and in Duel Links meta.
Just because a dumb fella such as yoruself says it's not worthy, it doesn't mean it's like that. Your deceitful opinion is pretty much irrelevant, buddy. LOL
The issue is there's no way to search Leng Ling other than Future Fusion into Panzer Dragon.
I don't know if I'd run 3 personally, but given all Cyberdarks really need to function is a Cyberdark and maybe a backrow, the brick potential's likely fairly low. Might be a problem with a build using Balance, though.
