Animation:
Dark March buff = A dark horse with a knight on the top.
Since it would be too hard for develolers to adjust the character sprite in the top of the horse, during the effect, the character would be replaced by the default Death Knight Novice's costume, maybe just a bit more detailed.
Cursed Fire Trail = Just... fire?
Like Knight's Curse fire but purple or green so it wouldn't confuse the players.
