Hello!
Looks like a solid collection for sylvaneth.
Personally I would magnetize the Kurnoth Hunter so you can play-test all different versions. If you don’t like the idea of magnetizing, I would go with 6 Scythes (for one 6 man squad) and 3 with swords.
The Spite-Revenants are excellent as 3x5 Units in the Outcast Battalion for the extra CP, extra Artefact, Drop count reduction and Battleline requirment.
In terms of a glade for your 2K list, I would go for Winterleaf and give your Arch-Revenant the glade Artefact and General trait. This will guarantee that almost anything gets destroyed when your buffed 6 man Scythe Kurnoth Hunters fight twice with 4 attacks each.
Good luck for your game.
