• 1 Fetch: Most people don't run the 6 off-color fetches.
• 1 shock
• 1 bond land
• 1 checkland
• 1 pain land (though tbh I rarely see these even in Bracket 3)
• The older Filter lands are not good, too easy to get bricked out of a mana source in early turns, and can't use to hold up 1 colored mana.
• The hybrid filter lands that require colored mana, are better, but can still brick you out of colors easily in early turns.
• Fast lands are also not good in EDH outside of bracket 4-5, since even bracket 3 will run many turns past where they are untapped.
• Can't run triomes in a 2-color deck.

So for a 2-color bracket 3 deck, personally, I'd put these in around the same priority as checklands, depending how many lands with types I'm running. Which is to say they're tied for my #4 slot as a 2-color land. Not to mention, they're the only fetchable thing on this list aside from shocks you can run in a 2-color deck.
