I think we are straying away form the idea of making a deck with Absol. I don't think we should be focusing on a milling deck, that is not what Absol is good for, and adding other milling cards won't win you a game!
Here are some things Absol G is good for.
1. T2 consistant 60 damage for 1 energy and energy gain.
2. Making an opponent choose between retreat or die! If they don't retreat, they die.
3. Absol G is an SP. We found with Luxape that pairing two random SPs together can make a devastating deck.
With those being said, I like Infernape 4 LV.X or Luxray GL LV.X in this deck. Not so much Palkia. With Infernape you can pick something up off of their bench and put it into play then Message of Ruin it or KO it. The ups for this is that Infernape can spread easily and you can use his power each turn.
With Luxray we can pull up a Claydol or something and Message or Ruin it. They either have to retreat or die, and it is not likely they will retreat.
Other than that, Message of Ruin is just great in general. If their main attack is out and threatening you, Message of Ruin it. Oh sure, they can still attack but if they do their turn will end and they will be KO'd. If they don't want their main attacker dying, they will have to replace it.
Another great thing about Absol is is that he can pt most anything within KO range starting T2. 60 damage T2, 60 damage T3... most Pokemon are out cold by then. Of course you have to discard a card though. We should use this to our advantage. At this point we could have discarded 2 Magikarp to fuel Gyarados, and on T4 there goes the last one. Absol will probably be out by then too but now we have a Gyarados who is very upset about his Magikarp in the discard pile.
What I'm trying to say is we should not keep pushing Absol into a milling position. Sure that is fun but what kind of secret deck would it be if it didn't win anything (which I can assure you, a milling deck will not).
Try to think outside the box, everyone! That is what a secret deck is about.
