I can't believe the things people are saying on this thread.
I don't understand how you're getting your numbers for pokemon going to the lost zone. Take the gigas matchup. Gigas, even with a dialga tech, only runs like 15 pokes or so. You would be lucky to get more than a few seeker'd pokemon into the lost zone via hurl. It is just too easy to clear out your deck and manipulate your hand. Regice, junk arm, bebe's, communication, collector then discard. You can't tomb under lock which means you'll be relying on seeker which means you won't be setting up. What are you going to seeker an uxie and wait 4 turns until you can use it? Also, strategic sacrifices make using twins tough. Through all this time, I am using drag off either taking prizes or forcing you to attach and retreat.
