But why green?
The answears are Tarmogoyf and Ancient Grudge. You need very few green mana sources and get a super aggressive card and the best single answear to any artifact based deck. Green adds to the deck without really impacting the security of the manabase.

Ancient Grudge, Steel Sabotage and/or Hurkyl's Recall are all good choices for the artifact spells. I like AG the best because you can just discard it to Dack and flash it back for just one mana. Also having at least one two mana artifact spell is really important.

Utility land or lands can be anything like Wasteland, Karakas or manlands like Mishra's Factory Tower of the Magistrate or Worldwake manlands. Id have a couple of Crop Rotation in SB for Karakas.. the chance if it getting countered is close to none.
Creeping Tar Pit & Raging Ravine are the worldwake manlands I think are playable. You cant play 4 copies of these. Two copies would be a max and then fill the deck out with fetch and or islands depending on how scared you are of getting locked out via Wastelands.
They hit the right way in vintage; Both kill Jace-decks and they have that evade effect that ends long games.

One mana counter should be either Spell Pierce or Flusterstorm depending on how afraid of stax you are.

Gitaxian Probe gives you so much information it is just silly. Playing it for life turn one and then landing a Delver gives out the impression your hand is filled with force'es. And if the opponent doesnt know you dont play Mental Misstep.. they wont really dare to play any cmc1 spells before they got two counters.

Gush is really good with Dack and the deck is full with high effect spells so you can get away with having few lands in play.
Fire / Ice is a decent spell that is AWSOME with Dack's ultimate. Tapping Trinisphere eot?

The deck can also be played without power. Id add two more Gitaxian Probes and more fetches & basics. Three Wastelands and a Strip Mine should be OK for a powerless deck.

Sideboard should include something like three to six Blood Moon effects. Moment's Peace is also really good and a card noone would expect. Volcanic Fallout is kind of the same card as Moment's Peace if you have Tarmogoyf in the sideboard.
