The double strike and fade is great, but the real benefit of Dreadwood is Spite Revs become Battleline. So you can double reinforce them for really cheap blocks of wounds. And with the strike and fade you can conga line them to get almost all 15 into combat without worrying about losing coherency (since you fade and reset yourself before the turn ends).
Something like this:
Allegiance: Sylvaneth
- Glade: Dreadwood
- Grand Strategy: Spellcasting Savant
- Triumphs:

With Hoarfrost, Arch Rev's +1 attack, and Drycha's +1 to wound aura, you could have 52-60 attacks at 3+/2+ rend 3. Which can delete pretty much anything, so that's fun!
