Angels and paladins – how to use them? There are also discussions about them here.

well, if we're talking about pairings... they're everywhere. Take any faction, for example!
Demons! The Devil befriended a cave demon – how? Well, the cave demon explodes a crowd, and the Devil finishes them off... yeah... and he also resurrects demons from other demons. Elves... elves are the most dangerous of all!!! Trees + archers, and they're also good at close range – GG to anyone. Dungeon – well, I think everyone knows about the Furies and the riders on lizards. And mages are something else... Golems and Gremlins in a team, and with the right skills, it's insane. Everywhere, there are advantages! And one more thing: you have to survive until you get to the angels... so even though I'm a fan of Humans, and it's my favorite faction, you still need a lot of resources to make Paladins and Angels.
