Your Kodachis were completely destroying Orf's Daggers (as sensibly used Kodachis tend to do). When Orfelius switched to Maces your large attrition advantage disappeared quite quickly though.

Next time make some Banishers or commit to Reapers to deal with Maces. Banishers are the more cost effective option and a better counter to Maces, but can be countered relatively hard by several other hover units. Reapers are less great vs Maces, but they don't fear defenses and are a bit more difficult to hardcounter.

It gets tough when the hovercraft player starts making decent amounts of Scalpels. They are pretty good against Reapers, Banishers and even passable against both tank raiders. More experimentation might have to be done with Pillagers, although it's probably easier to just facswitch and spam Glaives or something. That's pretty much what happened here: http://zero-k.info/Battles/Detail/284093

Rapier, Reaper, Weaver, Reaver, Raider, Radar, Reef, Raven... Hard to keep track, I know.
