Well. You can have as many cards as you like, but still just 4 copies of any card, apart from basic lands. So there's very little benefit to having 200 cards in your deck.

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...

> but still just 4 copies of any card

If you are playing Limited (i.e. Draft or Sealed decks) then you can have as many copies as you have in your card pool.

Although you may have some trouble finding 200 cards to use in a Limited event :)

Sometimes it's nice to spare yourself getting milled. :)
