Survival's the perfect example. What was one of the top decks in Legacy when it was legal? U/G Vengevine Survival. Sure, there were some G/W lists, and a G/B here or there, maybe a mono-green, but there was also a ton of blue. And that was then. This is now, in the Mental Misstep era. I've played against a few Intuition/Vengevine/Madness decks since then, and like every other deck it can just win off the back of being able to tap out every turn and have 12 cards in the deck that disrupt your shit.
Stoneforge Mystic's another example. It's a great white card. It's pretty good against blue, especially now that Batterskull exists. What does Owen Turtenwald do? Stick it in a blue control shell and top 8 a Grand Prix.
Aether Vial supposedly beats blue if you resolve it, right? Except that the primary deck that runs it is also mono blue. Seems good.
You get my point, right? There's very little you can unban, print, etc. that can't just be splashed into blue and be better. Most cards that beat your opponents' blue don't also kill your own.
