Avenger
Now that’s truly evil. Although you probably won’t be able to retrain all monks into horses, it reminds me of a personal experience. I was playing against an elf on a medium-sized map with a metro, and by the end, I had 36 paladins, which the dancers (and there weren’t that many of them) wiped out with a single hit (luck + Cursed). Since then, I’ve tried to eliminate elves as quickly as possible, regardless of the race I’m playing.
As for warlocks, chaos + irresistible + sorcery, and by week 3 at the latest, the game is over.
For other races, against elves, machinists are the best; a 3-shot ballista will destroy most archers. But you need to attack as soon as possible. In ToE, the Cursed enemy ability has been enhanced, so you can’t let the elves have the chance to add half of our units to the Black List.
