I find it somewhat funny that the "X" in "Explorers" is huge and gold (just like the Next Destinies logo). I guess the Pokemon company was reallly trying to promote the whole "EX" thing this time. I bet most fans didn't understand the "EX" In "Next Destinies".
I really want that Entei-EX. If I don't pull it in a pack, I'm just going to get it online. I've done it a lot before, in fact I'm awaiting Zekrom-EX full art right now (My rule: If you want a card really bad that's not featured in merchandise, which I'm glad regular Zekrom-EX is, get it off the internet. Use a reliable site, though. Only trust ebay if the seller has about 100% positive feedback) Groudon-EX is nice too. If Entei-EX isn't in the set.....
I have a feeling a lot of EXs will be featured again. Next Destinies had 6, so....
1. Darkrai-EX
2.Raikou-EX
3.Groudon-EX
4.Kyogre-EX
5.Entei-EX
6.Tornadus-EX
However, A North America could throw in another random surprise (Zekrom-EX and Reshiram-EX full art) and give us Thunderous-EX and Suicune-EX to complete the trios.
As far as theme decks go, if I get one (I'm not sure about it yet), it will be Zoroark.
