Unholy Annex / Ritual Chamber
Enchantment — Room
(You may cast either half of this spell, unlocking the door to that room when it enters. This card has the abilities, colour and mana cost of that room. As a sorcery, you may pay the mana cost of a locked door to unlock it. The abilities, colour and mana cost of that door are added to this permanent. If this enchantment enters without being cast, both rooms will be locked. Copying this enchantment also copies the locked status of the rooms.)
Unholy Annex
At the beginning of your end step, draw a card. If you control a Demon, each opponent loses 2 life and you gain 2 life. Otherwise, you lose 2 life.
Ritual Chamber
When you unlock this door, create a 6/6 black Demon creature token with flying.

I feel like Unholy Annex / Ritual Chamber is a must in any demon deck to an extra card every turn and its does another 2dmg (or more depending on your board)

Cats In Claws Out

What an amazing performance for the first time with the deck, 2-1-0 on the first local tornament putting it on 3rd from a poll of 8 players. Here is a more indepth analysis of the matches:
1st match (Gates): 2-1 by far the easiest match to go up against even when they sideboarded in Authority of the Consuls and dropped two of them, we still made quick work with our early swarm of cats.
2nd match (Golgari Aggro): 0-2 where to start, I didn't have all the sideboard finished for the deck but holly hell the Banishing Light is a swiss pocket knife for these match ups if you don't have the board wipes or the reanimates. My recomendation for these type of decks is for you to take a more defensive roll on the second and third match, your cats can wait and slowly grow larger, you need to control Unholy Annex / Ritual Chamber and the Archfiend of the Dross which are the biggest threats by far. Really learned a lot with this match up.
3rd match (Golgari Aggro): 2-1 I know it might come as a suprise but you really learn a lot just by one match up. When I was faced again with the same deck I knew what hands to keep, what to sideboard in, the deck really shined from both sides (aggro the first game/control on the other two). I cannot stress this enough Banishing Light is something you want sideboarded to deal with any threat that appears it's supper versatile.
I've done some changes to the sideboard and I'll keep you posted.
