1-8 Ace of Beasts . . . --> Beasts Deck . . . --> Darkmoon Card: Blue Dragon
1-8 Ace of Elementals --> Elementals Deck --> Darkmoon Card: Maelstrom
1-8 Ace of Portals . . . --> Portals Deck . . . --> Darkmoon Card: Twisting Nether
1-8 Ace of Warlords . .--> Warlord Deck . . .--> Darkmoon Card: Heroism

The problem with these decks is that you'll end up with a whole lot of duplicates. The more decks you make, the smaller this effect, but it still pays to know just how many cards you can expect to make.

To this end, I programmed a sim that randomly draws cards and checks how many duplicates you end up with for a given number of decks. This is obviously only valid for creating decks within one set (i.e.: classic, TBC, WotLK, Cata). Here are the results:

This makes a random Pre-BC darkmoon card. I've gotten ace of beasts as well as two of elements.

This is also good for leveling, since the last 15-20 points before lv 300 are pretty much required to be done by making the ink for this and making this.
