No benefit except that it is awesome.

And anything involving Shadowborn Apostle:

444 Shadowborn Apostle

1 Reaper from the Abyss

1 Sire of Insanity

2 Griselbrand

4 Cavern of Souls

214 Swamp

There are probably better lists but I like the simplicity of this one and the 666-card deck.

Is this from Unhinged?

Unsure if you are serious, but no, it's from an actual core set. Some battle of wits players did "okay" in a couple of tournaments too.

There was a modern legal deck which used this card and birthing pod (now banned) and actually won a decent number of mtgo events: http://archive.wizards.com/Magic/magazine/Article.aspx?x=mtg...
