Horror Mark is nothing to write home about
: most horror attacks are too weak to do anything to a genuine SC, though one item or two give a nastier Horror Mark, if memory serves. Horror attacks seem to be pretty uncommon too: my Pretender, despite an Horror Mark picked up carrying various artifacts, has yet to see an horror attack after more than 20 turns (other Horror Marked commanders are doing just fine too).
Curse is more annoying, but how bad it is depends on how Regeneration and Curse work for affliction odds (figures are 10% for Regeneration, and +25% for Curse). And of course, you still need to hit the cursed commander for the curse to do anything.
