Professor Birch!
You eed to think of altering your Supporters to include this all important card with DWD gettin so popular. If you Top Deck a Birch, you get a fair chance at reloading your hand and possibly giving you that little edge you need. The early game issue is honestly Umbreon*. Absol can be mangaed, but with the *, TGM, and Absol goin turn 1-2, it really kills!
Mawile CG also can be somewhat helpful as you can Mine for Cessation which can stall the Murkwo Swarm a bit and can stall the UMBY*! Another Opiton is Mawile PK as it can help thin the deck a bit and cause you to not get Benched. NTM it can kill their hand as they are building it up with there supporter use.
The Techs are there, but it is again as you said Mike, getting it out! Mawile PK with Rayquaza EX d could be nice as you can get the Ray out and then maybe get a chance to power it up!

Forgot to add Spinda! If your are Playing TTAR or Weavile Variants, this can be a great Game Changing Card! Spinda + Basic Dark = 40 damage to Absol! So you can 2hko Absol which can slow it a bit, esp if you go first! If you try Spinda, I suggest playing Crystal Beach as well! GL!!
