Secondly, all I'm seeing about Port is meaningless hyperbole. Saying Port wins games and creates tempo boosts doesn't indicate how it actually does either one of these thing.
Let's start with a fundamental understanding of Port. Port costs two mana to use: The one you spend to activate it, and the one you aren't able to draw from Port because you're using its other ability. Port denies your opponent of one mana if and only if they can't spend the mana on an instant or activated ability. This, in a vacuum, is not a tempo boost. This is a tempo loss.
To gain tempo from Port, you need to be drawing a significant advantage by stalling for time, which Goblins admittedly does. But Goblins only does so when either it has an Aether Vial that's building up counters, or it has a relatively pressure-free board and is playing an opponent that, like most, has a worse long game than Goblins.
Now. Of everything in the DTB forum, the Landstills are probably the only time where Port is undisputably great. Against Tempo Thresh if you're mono-red, they can be useful also, keeping opponents off of either Pyroclasm or Tarmogoyf in select situations. They will also be useful on occasion against anything that's struggling to draw land.
Now. Weigh that against the drawbacks. Every time you're using Waste/Port or Port/Port to tap a land down, it could be cycling Gempalm, playing Piledriver, playing Mogg War Marshal, or if you're RB, playing Warren Weirding. And every time you hit Mountain/Waste/Port, you have to factor in that if there's a Chief in your hand, you could be playing him. You also mulligan more hands that start without red sources. You also have less explosive power with 4 mana on the board, where it's a lot more likely you won't be able to play Warchief/Any 2-drop on the same turn.
The drawbacks of it just don't make it worth it for me in 2-color. I'd much rather have my 18 red sources and be more consistent and run a hair less in the mana denial department.
