i get the feeling that this is going to push dusknoir for time as the tech for many GG decks but i have my doubts as to it's effectiveness. the thing is, there has already been a card out for some time with a very similar power and i have never seen it teched into GG. that would be shiftry, and if it doesn't work why should omastar? yes i know shiftry is flippy and it only affects one at a time but it's power is re-usable plus its' dark nature makes it very useful against ghost types. plus shiftry, like dusknoir, has a basic that is searchable. i think people are going to find omastar occasionally difficult to get into play, a real liability for a 'surprise power' tech. in other decks, especially ones trying the omastar-tgw disruption combo, i think it will work just fine, it's just in GG i don't think it is going to be as good as people think.
