Fanatic's Scream

I love Haunting Scream. I love Madness + Devour combos. I love Piercing Grief. I wanted a deck that could be playable with all my favorites that I built myself. Here it is, any feedback is appreciated.

Xenan Lifespeaker is there mainly for early blockers and to give the fanatic twins lifesteal.
If you manage to get lifesteal on a Xenan Lifespeaker, then the effect at the end of turn also has lifesteal. It is hilarious and can snowball quickly. It's easily removed, but can be brought back for one big swing-y turn with Haunting Scream or Dark Return.
