Well, theoretically speaking Devil Advantage nets you +1 card (works like unrestricted Nice One) but practically you should not run more than 2, as it becomes a dead card should you draw it early.

Noisy Danceroom, on the other hand, works like a filler card to me. I only ran 2 of it because I didn't have enough Magical Goodbye, which should be run x4 for any 72 Pillars deck.

Now if we're talking about 72 Pillars, we're talking about Saturday Night. This is the trademark of 72 Pillars; it allows you to do a second battle phase on the same turn--thus awarding 72 Pillars a title for being an explosive deck. I strongly advise you to run at least 3x Saturday Night, if you refuse to run 4. Not to mention that it has the attribute 72 Pillars, so you can put it into Astaroth's soul early game.

There are a lot to discuss about building a particularly strong deck, but you could always visit this page to take a look at regional championship deck list if you're looking for some insight.
