Mana dorks

[Hakuu]

My buddy used {mind sludge} and tryed to count his mana dork as a swamp. Is that allowed or does it only count basic lands?

It's only your basic lands.

[Hakuu]

How about cards like {Pristine Talisman}
Can u tap it without using the mana it produces to gain the 1life

[Poof]

It says add 1 mana to your pool doesn't say you have to use it.  You can tap all your lands too if you want

Yep

Only land cards that specifically say "swamp" in the type are considered swamps for effects like mind sludge. This is usually going to be just basic lands, but older sets will have non-basic lands with types too like {bayou} way back and as recent as things like {watery grave} in Ravnica. They are also swamps - it says so in the card type line! Other non basic land that does not say swamp on that type line is not a swamp, even if it produces black mana.

He was trying to count his swamp Mana dork myr

[scarsabrex]

which isn't a swamp... unless he managed to turn it into a land and have a {tomb of yawgmoth}

Black mana {B} =/= {Swamp}
