Monkey Attack Said:  You see, this deck uses dark feraligatrs mean power and espeons strength to beat up the opponent bad.

Gloom Said:  Hmm… well, there really isn’t very much synergy at all between Dark Gatr and Espeon.  The only real synergy here is a synergy of weakness – Espeon will cover Gatr’s weakness to Crobat.  Still, I don’t really think it’s worth playing both together…  Whyyyyyy don’t we keep the Espeons and drop the Gatrs?  Unfortunately, without King, the Gatrs are really quite useless now – no point using them with Noctowl, because they effectively due the same thing – disrupt trainer retention from Eeeeeeek.

So we’re going to add in two Murkrow, and three darkness energy.  This’ll let us lock nicely.  We’re also going to add in a 4/4 line of Noctowl – this allows you to see when to mean look, and when to use Espeon to attack.  The key?  They’re all free retreat.  So we’ll also max out on double gust. 

Your drawing engine is mostly fine, but I’m gonna add in some more berry/band and I’m going to give you some Trader.  Also, rocket’s hideout will no longer be needed, so that will give us some wiggle room.  

Heeeeeere we go!

There we go!  It’s quite a bit different from your first deck, but since Slowking has been rotated out, the environment is just very, very different and a fix like this is necessary.  That should run very, very well and you should have little problem disrupting the opponent with an admirable consistency.  Good job!

Thanks for sending it in!
