It has been a very long time since Ive posted a tip on pojo and this is about some old friends of mine. On to the article.
 
Apparently a lot of people have been having trouble with all the chaos decks running around lately.  I can understand this because i myself used to run a chaos deck and i did well with it.  but i got bored with my chaos deck and decided to move on to some sort of anti-chaos deck.  as i was looking through my old deck lists i came across the ultimate in chaos destroying decks, a gravekeeper's deck.  Gravekeeper's decks are insanely powerful when used right especially back when they first came out.  Necrovally shuts any chaos monsters down making them useless.  A gravekeeper's deck completely shuts down the whole strategy behind chaos decks.  Most of the chaos decks I've seen run a lot of smaller monsters and painful choices.  with necrovalley on the field it really will be a painful choice.  i know a lot of people are going to say "but your opponent could just Harpies, or MST it, or breaker it, or activate imperial order on it" well no crap.  thats the risk you run with these types of decks but thats not a reason not to use them.  also cards like magic reflector really help, Ive gotten two of them on one Necrovally at once.  you will also need to run a few seven tools of the bandit and at least one dust tornado to counter Imperial Orders and what not.  an added bonus with these decks is the fact that Gravekeeper's are meant to swarm your opponent.  with the gravekeeper's spys' effect, gravekeeper's chiefs' effect, and Rite of Spirit's you can fill your field up with 2000+ attack monsters in no time (assuming Necrovalley is on the field). 
i guess all I'm saying is Necrovalley decks are incredibly powerful and fast decks that work really well in the current environment and almost any met game really.  so give it a try.  I've shut down chaos decks completely with my deck

p.s.
you're gonna definitely wanna add a Card of Safe Return in the deck.  with all the special summoning you can do in a single turn it can be awesome.
