I think that people are over reacting with the whole Lost World thing. I've played a LostGar deck before. It's like with VilGar, just keep the Pokemon out of your hand like you would trainers.(there not going to always have a Seeker.)
I don't like the set all that much, but I can't say I hate it. The Rev Holo Energies are going to be awesome, so is Pachirisu, and some more cards will be worth it, also, I am still going to the Pre-release with my brother.
I know those of you who are saying LostGar is going to dominate are entitled to your opinion. So if you think it's going to do so good, why don't you play it? Heck, the more people who play it, the more people I beat...
