Garruk vs Liliana duel decks

As mentioned in a previous post on Jace vs Chandra duel deck, I also have the Garruk vs Liliana duel deck for the Magic: The Gathering (MTG) game. You may want to look at the previous post for a picture of the box, along side that of the Jace vs Chandra duel deck. The decklist for the Garruk vs Liliana set can be found on Wizard of the Coast's website.

This duel deck set was the second set to come out to include planeswalkers - the first one being the Jace vs Chandra duel deck. Wizards of the Coast do not include a planeswalker with every one of their duel decks, but they are increasing the frequency of sets coming out with them.

As mentioned previously, I enjoy the way you can just buy a set like this, and start playing against an opponent. Unfortunately, all is not balanced with this set.

I have mainly playtested this set with SpecialK - with SpecialK playing the Liliana black deck, and me playing the Garruk green deck. I have yet to win a game playing the green deck - even though I in most cases I am able to play a land every turn. I find the problem is the black deck is very quick in getting creatures out, and once the creatures are out, they have enough evasion to get past the creatures in the green deck. If the black deck looses a creature to the graveyard, then they can cast spells (including Liliana's ultimate planeswalker ability) to retrieve the creature back from the graveyard.

This goes against what most duel deck sets are appear to do. Every set I have purchased so far is balanced against its opponent's deck. Liliana's black deck has an advantage over Garruk's green deck. I am not talking about the occasional lucky win, but the black deck consistently defeats the green deck in reliable manner. This may come down to me not knowing what to keep in my opening hands, and not knowing when to mulligan my starting hand. If anyone has any insight to win more regularly with Garruk's green deck, I would appreciate your comments below.
