Starmie EX
Starmie EX is one of the few archetypes that can rival Pikachu EX in terms of quick-kill potential and flexibility, but it loses a few points due to its status as a Stage 1 Pokemon. This means that its job can't be completed on turn 1, even with a good result from Misty, due to the need to evolve a Staryu, which. Still, don't let that make Starmie EX seem like a poor-man's Pikachu EX, as Water brings an entirely new set of support that can really differentiate this archetype from the competition, and a fully set up Starmie EX can be a frightening foe, in part due to its 0 energy retreat cost.
