Against which factions is it easier for demons to fight, and against which is it more difficult?

when was he on the 4th flag?))
maybe))
let me guess, you were on the 3rd flag and playing as Nazir) and the bridge guard was weak (not druids/archmages or forest archers >_<))
otherwise, you wouldn't have time to break through to the center, and that jerk would already be in the treasure room on the 4th day =P and would gather hi-tech units)

if it wasn't that strategy (not with a mage), then what did you do?)
