I know it's a bit early to be brewing with Phantom Gate cards but there is obvious synergy between these cards and I thought I'd make a draft and see where it goes.
Note lock decks are not my typical style so I'm not sure how to build the best one.

Strategy:
The strategy is to lead with Gengar-EX and have Phantump and possibly Skrelp on the bench. Turn 1 attach a psychic to Gengar. On turn two you want to evolve Phantump into Trevenant and attach a DCE onto Gengar, play down a Virbank and start attacking with Hallway of Darkness. it does 60 plus poison and then switch to one of your bench pokemon. You switch into Trevenant starting the item lock and if you have Dragalge you're opponents active also can't retreat. Find a way either through Float Stone, Escape Rope or Switch to retreat Trevenant every turn and repeat the process. Beartic is in to hit landorus and Pyroar when needed.
It's a rough list but let me know your ideas.
