Mummy. Especially upgraded ones.
It always feel neglected compared to flesh recluse... that resembles me so much.

That aside, it can make nice combos with Rewind+SoR (what I'm using to grind arena gold), while preventing one kind of common CC a.k.a. rewind, especially vs ghostmares in rainbows.
Plus, if you got a rewind from your SoSe in your rainbow you can get a monstrous CC machine... It provides more fun and surprise than flesh recluse in every way

Overall Mummy sees use for both generic and specific purposes, and can mess with your opponent's mind in pvp...
