[@Acid Hippie] Cyberdramon doesn't evolve into Beelzemon. At least not that I'm aware of.

He doesn't.

A line to end with Beelzemon would be Impmon > Devimon > Skullsatamon > Beelzemon (Game based)
or Impmon > Beelzemon (Anime)

If you wanted to keep Gazimon you could go the Gultmon route.
Gazimon > Devidramon > Mephistomon > Gulfmon
