"Son Doong Cave is the largest cave in the world, it's name means "Mountain river cave" in vietnamese. 
How would it play if it were an MTG land?
Maybe it could be the first flip land. Produces green and blue, then when certain conditions are met, it flips into white and black(from the second picture). Maybe it flips when you have at least 2 mana of a color it can currently produce. So for example, play it, it makes green and blue. Float 
/
/ and it flips to produce black and white.

If you can justify that Son Doong Cave can generate 
and 
because it has plains and swamps inside, then why would it not generate 
as part of a mountain? It's easier to claim that the cave includes all land types than to suggest it can't produce .

That's right, x754, the cave is part of a mountain,The wind whistles in the cave, so it might produce white.It's in a jungle so it would produce Green.It's also an underground cave so it would produce black, it has lakes so it would produce blue.In my opinion, I'd say it would produce and you gain 1 life.

By that logic:
- The wind whistles on mountaintops, so all mountains are plains, including volcanoes.
- All caves are underground, so all caves are swamps, including the warm cozy ones like hobbit holes.

Hmm.. Good question. Enters the battlefield tapped. Return two lands you control to there owners hands. Taps for G+R+U?
