All fair points, and they’re definitely agreeable. But are you saying it’s one-sided issue? Do you never lose to drawing plains over blue land or spell in more conventional games?

I definitely agree that fetching duals against Waste is important, which is something I do all the time with this deck. However, one feature this manabase has from most others is the ability to play around Wastes depending on the fetchland and basic draws or through Wastes with dual lands. The deck has 19 U sources, which is a very high amount for a main color in legacy, and 16 for its secondary color, which is very unusual. While the situations don’t happen frequently, they do happen, and having that many basics is helpful against random jank you encounter since the deck is so slow. At Milwaukee, I played against three lands decks, and this many basics means you can almost always ignore their Loam shenanigans and Entreat eot or in your upkeep, depending on how many Ports they have in play. Against rug Delver months ago in a local dual land event he had Waste lock and lethal on board in three turns amd I had a Top and Island in play. Fetches into basics and the eventual sweeper dug me out of that hole and I was able to destroy him with CB, then Jace, then Batterskull. In the same event I played against an aggro loam list, and both the swiss and top 8 were won handily by stabilizing my mana with basics then Entreat, which they basically can’t beat.

Sure, if I am playing against combo, Plains is easily the worst land, but I am very comfortable with the combo matchups with this deck and with the frequency of this happening it’s not a huge concern.

But I do agree that for other legacy decks your points are very valid. Miracles is the only one I’d deem a true “control” deck (in that the goal is to go to the late game by controlling the early/mid with counterspells), most blue decks are aggro/control (I put RUG/BUG/Stoneblade Variants/etc in this camp) and thus it makes more sense to have “perfect mana” when you need it early then more mana later.

I suppose that’s fair, and the difference is probably too negligible to just sideboard the Plains.

I won both games. The Standard win was way more convincing, while the vintage involved my opponent not having many counter spells. That’s really not the point at all though
