These are my guesses.
Seal: Choose 1 of your opponent's actice pokemon's attacks. That pokemon cannot use that attack as long as the Seal Counter is on it.
Quake: Maybe not able to retreat? (because it's almost impossible to escape an earthquake)
I think that the DX-on will be one of the best things that ever happened to us. Don't have any CG luvdisc? Try Plusle. Missing ludicolo in a non-ludicargo deck (with macargo)? Try jirachi or metagross d. Need a dustox ex-wannabe? Try altaria. (DX) Need to retrive good energy: Use camerupt paired with power tree. Need a copycat? Try claydol. Need a card to combo with porygon2? Dusclops is your awnser. Want a mini-pidgeot? Use mightyena. Then comes Ludicargo. There are much more. If you don't understand a lot of typing like this, I mean that this new format will be great, with some of the best cards still avalible.
