I would lose both computer search first! You can only have 1 ace spec card in a deck... also groudon is ok in here but not good enough... drop both and then drop a terrakion ex for 4 energy switch... drop the ultra balls for heavy ball since all of your pokemon have 3 or more retreat... you...
So your saying that when you know your opponent has ghetis and you are holding 2 catcher, a plus power you will need for later, an energy switch that if you use you lose your attack for the turn you would play all of those trainer cards to avoid them drawing more cards even though it can cost...
Maybe you play in a better venue... for the most part in my Meta people will play "N" when I have been suporter dead for 3 turns, there are probably people in your area that do the same, these people do not think when they play. Those are the people that would use ghetis and not really look at...
I think this card brings more skill to the game... when is a good time to play Ghetis? Did you just watch your opponent play out 3 trainers and not use a supporter? When you used Ghetis did you see a Ghetis in your opponents hand, if so do you play all of your trainers that turn to make sure...
If you browse the deck help section I f this site you will find your answer... click a deck , read the comments... and read the deck lists ... you will find a core for any deck you want by doing some research...
