Most of the LvXs that I've pulled have been from tins. An example of this is last week when I bought two Darkrai tins. The first tin I pulled a Lucario LvX from the mysterious treasures pack. In the second tin I go a Gardevoir LvX and a Dialga LvX from their respective sets. Most of the other rares I pulled were also good such as the GE claydol, SW Wevile, etc. Unfortunately, I only pulled three trainers so I guess it almost ballanced out. I also pulled an Electivire LvX out of a Lucario tin a couple months ago. I guess in my case I just get luckier with tins. However, this is probably just luck.The odds might be different for tins, though. Once in a Lucario tin, two of the packs I got had the exact same commons, rares, and reverse holos in the exact same orders, the only difference was the uncommons. It was weird, lining up the packs in the order that they came in: "Gibble, Gibble, larvitar, larvitar" and so on.
