It's not quite perfect yet, but really liking how it is playing.
I'm a strong believer that Speed and +1/+1 for all other troops are the perfect sockets for the cyclops.
I will try to keep the speed gem in mind and see if it would have been better in my upcoming games. Lifedrain has saved me a few times in the more durdly matchups though. One epic game against the plant dude comes to mind.
