Nothing funnier than seeing a O&G outshoot wood elves. Liking the idea, i still think you should have something very heavy hitting for the counter attack. squig riders may be suited to this list for a counter attack.
Don't, after rolling that final 1 too many, flip out, climb up on the table and jump up and down on your opponent's models screaming 'APOCALYPTIC BARRAGE, MOTHERFUCKER!!!'.
