well, i've had the pleasure of testing out a blastex deck with proxies against a few other variants, mainly Primeape (rampage), ampyex, and a bex deck (all RS-on). here's the results:
Primeape: the speed of this deck is unmatched by most decks in the future format and even some in today's modified. enough draw power leads to more pokemon tools you have in your hand, making Primeape a lethal weapon. when i faced this deck, i barely got the chance to abuse blastex's power due to the speed Primeape was gotten out and the drawing power that was put into the deck got the pokemon tools to power up Primeape fast. needless to say, the deck was beaten after a couple of rounds. i tried a few times more, but the speed was just too fast for blastex to catch up with.
Ampyex: since we're both running 3-stage lines, this battle was to see who could get out their big hitter first before the other guy got his out. naturally, if ampyex got out first, blastex would be put into a tight position, which it was in one of our games. when both pokemon were out, my opponent didn't want to send out ampyex because it could be knocked out easily by a powered up TA's Walrein if i had the chance to use it. so, i had Milotic on the field as i tried to keep on searching for Archie so i could bring out TA's Walrein. problem is, though, my opponent's main attacking pokemon was Raichu ex. in a matter of turns, he was able to take out Milotic with a combination of ampyex's pokemon power and Raichu ex's constant run of dazzle blasts. when i switched out to blastex as one of my last guys, Raichu ex's mega thunderbolt took it out in one shot. needless to say, i lost every match.
Bex: this deck was fairly easy to beat, although i did lose one match due to an insanely crappy hand. once again, 3-stage pokemon on each team. there really isn't much to say here, since any decent water deck can beat bex if it's fast enough. milotic was able to hold off most of my opponent's force until Rayquaza ex nearly knocked it out, when i played a Briney's Compassion and returned it to my hand. i then sent out a semi-powered TA's Walrein. i then abused the crap out of Blastex's power to beef up TA's Walrein. then i played Milotic on a benched Feebas to heal everything, then knocked out Rayquaza ex.
in short, blastex hasn't worked well for me in the main decks that are going to be played next format. Primeape is too fast and Ampyex is too powerful. however, this will bring the reign of Bex down in the modified format.
