Blastoise EX

Blastoise EX has a bit of an identity crisis. It has more damage-output potential than Venusaur EX, but it lacks the bulk and recovery of its Grass Type counter-part. It has a bit less of an energy-issue than Charizard EX, but it lacks the sure-kill capability of Pokemon's secondary mascot. All-in-all, its niche falls a little bit short of much of its direct competition, making it the mediocre middle pick when building a deck around the Kanto starters.

But Blastoise EX does have one major advantage over the competition: Misty. While Grass and Fire both have energy-generation options, Blastoise EX can potentially set up a lot faster and with less opportunity cost with a few positive coin flips, meaning it can hit the field fully set up as quickly as or even faster than the competition and deal tremendous damage per hit if it can score 5 energy. Misty is a fickle card, to be sure, but at times it can be worth the risk to make Blastoise EX an offensive juggernaut that has damage that surpasses Venusaur EX without the energy-loss drawback of Charizard EX.
