Holmegaard is a piece of HB ICE that hasn't got much popularity recently, which is a bit sad, because this is not a bad ICE by any means. Let's compare it to its more popular cousin Ichi 1.0.
5 strength is nothing to sneeze at compared to Ichi'1 4
Trace 4: No access is a fantastic subroutine compared to Ichi's Pitiful Trace 1
EDIT: Trace does stop Indexing, or other "instead of access" run events
Program trashing subroutines are always welcome
is not a bioroid, cannot be clicked through like Ichi can, will almost always punish a facecheck with a trash
7 rez cost is a little steep
Program trash is limited to an ICEbreaker, which is marginal due to the fact that you always target icebreakers with trashing subs anyway, save for the occasional Magnum Opus
Overall I think this is a pretty good ICE that complements HB nicely.
