User blog:Tagion/"Demonic Sanctum" - Size 3 72 Pillars Deck

So...I fell in love with Rucifiel.

I mean, he's the Fallen Demon Lord. And his ability is pretty solid. Plus the Double Attack with a sweet 8k. The only thing is his 4 gauge Call Cost, but I can live with that. So I decided to build a deck around him.

This was mostly just to show off something I made, but  I'm opening a little challenge.

I want to see how you'd turn this deck that was made for fun, admitedly, into a competitive deck. The only rule is that Rucifiel must still be the Buddy/Focus of the deck.

Other Size 3 were used just because. I'm not well-vised in Magic World conventions, and I am willing to be criticized and learn from my mistakes. Any constructive criticism is welcomed.
