Hiya,
Jay, the ex should be:
Blaziken EX
Swampert EX
Blastoise EX
Charizard EX
Venusaur EX
Jirachi EX
Kyogre EX
Groudon EX
Yeah...9 ex, if WPM's prediction is correct. Better Hope the set have some decent trainers too...Reprint Admin, Stevie, Copycat.
And...Blaziken ex is great! The weakness is not water! And there's no other psychic pokemon that't too great to kill it. The attacks ain't that bad... 4 for definite 100 damage is nice. Unless you're fighting Wailord Ex, it's a different story.
cya.
