Anything in Arcane Power for Fey Warlocks?

[Klaus]

Now that I got the Builder update with Arcane Power's goodies, I see a very nice Fey Warlock Encounter 3 power: Sprite War Call. Sure, the damage is rather low, but for my rogue/warlock what's important is the range (10 for feylocks) and those magic words "grant combat advantage".

All I have to do is refluff the "army of sprites" as a "murder of crows" pecking at the enemy to round out my "Raven Pact" (all hail the Queen!).
