That Zeraora looks beyond legit! Such impressive work. I think the first attack might be a bit powerful for BW-era - it's only on a Stage 2 (Gallade PLS) before migrating to a Stage 1 (Huntail PRC) in early XY-era. Plasma Shot will probably consistently be hitting 180 damage with the current version of Research Base, but I'm not sure if that's too much. While I don't feel your basics engender a Big Basics archetype, I think the Trainers do. At least, they're advantageous for big basics and more difficult to use in evolution-based decks. There will inevitably be benchsitting Plasma basics that would be able to abuse Team Plasma's Assignment, whether in this set or in another. Even without them, I would gladly load my bench if it netted me a free +5 / +6 cards per turn - especially considering there's a basic Rotom that can turn other mons into Team Plasma Pokemon if I want to elevate that draw engine. With Research Base, do you specifically want to provide free Energy acceleration? The thing is, I think Colress Machine and Research Base are two different kettles of fish, and I think Research Base is the better one. This is because: Colress Machine grabs Special Energy from your deck, meaning once you've used a Special Energy and it gets discarded, you can't accelerate it again. For Research Base, you can keep accelerating the same Special Energy. 4 Colress Machine could accelerate 4 Energy. But 4 Research Base can accelerate much more than 4 Energy. I think the issue is that you're accelerating Energy on a Stadium, and Stadiums are more prevalent and long-term than Items and Supporters. My idea would be to get rid of the energy acceleration entirely, and instead have the effect let you swap an attached basic Energy for a Plasma Energy in your discard pile (for example).
