There's no way TPCI would make a card that lets you take 6 prizes at once without it being complete trash. As for the dedenne GX, we needed a new draw staple once lele rotates next year, and I'm glad that they are going for draw instead of search this time
If this is a draw pokemon w/ a better version of shaymin-EX's ability, nowadays, it could serve to compliment the new search staple, Magcargo from Celestial Storm(its ability effect was only on a Stage 2 in shaymin-EX's time, making it hard to pull off then because it required a Rare Candy to pull off, but Magcargo is a stage 1, so the effect is easier to pull off now, but... ), and that would lead to a near-broken combo... Near-broken because of the ability-busting Weavile from Burning Shadows, insufficient HP on the end of the Magcargo(The GX obviously has to have a high amount of HP, or else why would it be a GX?), which also requires evolving from Slugma in order to make it one BEFORE you can use it, among other factors that ensure the combo can more easily be busted by other cards' attacks than being truly broken... If the combo is busted, and you have either but not both ends of combo, your draws won't be as efficient, and there's no guarantee you'll get the card you wish before your foe does...
^ Amazing idea, but at this time, take it as a grain of salt, because if it's true, one has to wonder: "is the ability broken if and as long as a stage 1 or lower ability-based searcher is in the format?"
