- Which faction is stronger? (Necropolis, Tower, or Conflux)

but having 80 Phoenixes in his army didn't save him, not to mention the other minor details.

Hmm... and how long did the game last? Judging by the number 80 Phoenixes, it lasted about 4-6 months.
I think that switching to a normal opponent instead of an AI one will make this trick not work.
Set Conflux and Necropolis against each other, I'm sure Conflux will easily defeat Necropolis!
