@TuxedoBlack @Vulpix Yolk @Sabaku I think these are some well thought out posts and have all good points. What I think is the most prevalent from Item lock is not the lock itself, but the counter measure of energy disruption. I've tested a lot of games and the lock really doesn't matter as long you have energy on the board. More specifically, if
basic energy remains on the board, the lock, though annoying, can get overwhelmed. My hope is, though it is a long shot, is that new Carbink card might help some.
Vespiqueen deck has players counter measuring with Enetie (AT). I think out of all lock decks, the Trev deck presents some challenges. But I don't think the Trev is as potent if it can't discard basic energy for a round or two. I think it will give enough time for cards like Yveltal and Manetric to charge up. What card I think might see some play is PFC because you search for the pokemon under item lock distress. Also a rouge Silent Lab is a clutch play off a Skyla. Silent Lab really messes with those slow draw decks.
In expanded because there is Archelops, I believe it holds some players at bay, and it is one of the reason why lock decks can be a tough play at times.
Now, having said all this, I tend join the item lockers when practicing and playing. I think the reason being is that pokemon gives very easy and simple mechanics to wipe out approx. 2/3 of some one decks in a single turn. All the other ways are more complex mechanics to stop item lock. By providing these simple mechanics, I don't see why pokemon doesn't adjust the game for simpler mechanics in the other arch types, but that's another conversation.
I do tend to practice with item lock decks and practice against them. I think you need to fully understand the decks to play against them, but with all the locking decks out there it is a definite reach for trainers to counter measure them.
