I see comments like this a lot. Not trying to pick on you, wonderful_whismur, by singling yours out.
The
best support for a Stage 2 is a good Stage 1 from which to Evolve, especially partnered with a good Basic. Not a lot of examples of that, but probably the most recent is when we had
Zubat (
BW: Plasma Storm 53/135) and
Golbat (
XY: Phantom Forces 32/119;
Generations 31/83) backing up
Crobat (
XY: Phantom Forces 33/119). The other best support is the-powers-that-be slowing down new Basics, so at least in Standard, once the older ones rotate out Stage 2 Pokémon have time to setup. That's all they really need.
The "support" we actually get that has worked to make them competitive tends to go too far the other way.
Broken Time-Space and even pre-errata
Rare Candy sped things up for them, but swung things too far the other way. Which meant non-Evolving Basics suddenly were bad, or
worse, once R&D tried to compensate it just seemed like
everything was broken (though in reality, it was just the top performers in each area). Sticking to more recent stuff, I can't say I'm thrilled with cards like
Archie's Ace in the Hole (the reason
Blastoise had one last hurray) or
Forest of Giant Plants (...). I've loved various
Vileplume and their propensity for Item lock since
Dark Vileplume, so it says something when I'm telling you I don't like
Vileplume (AOR) and
Forest of Giant Plants.
