The Altering Cave, in Pokemon FireRed/LeafGreen is pretty much useless until you get mystery gift. Before that the only Pokemon in there are Zubats from what I have seen. There may be others, however. Once you get mystery gift, though, some fairly good Pokemon can be found. These include Teddiursa and Stanler. They are not that rare, but they are better than Zubat.
List of Pokémon in Altering Cave:
It's a cave that appears to the left of the Trick Master's house. I'm pretty sure that you need a special Gameboy Advance expansion for it to take effect (which would be hard to find nowadays) in which it replaces Zubat with some different Pokemon. They aren't REALLY rare and can be found elsewhere, so it's a fairly pointless cave.

You have to surf to the middle where there is a small island and cave the legendaries are in the caves but you you only have one chance to catch them. The Pokemon Mespirit is hard to catch because it goes around sinnoh and you have to follow it and it runs away so make sure to have the movie mean lock so it can't flee
This article is about how to catch Terrakion in Pokemon White. First, prepare some Pokemon that are around level 40 to level 50. These Pokemon should have status attacks like hypnosis. This makes your team able to catch Terrakion. Next, go to the pokemart and get some pokeballs. Make sure these pokeballs are either dusk balls or ultra balls, because most legendary Pokemon are hard to catch and dusk balls can be used to catch Pokemon in caves. This makes you able to catch the legendary Pokemon Terrakion. When, go to victory road from the Pokemon league. After, you go there, go into the cave on the right. Next, go take the left staircase down. Then, head left and you'll see a big cave. Later, go into that cave and you'll see Terrakion. Go up to that Pokemon and try to catch it. After you caught it with status Pokemon and pokeballs, you'll finally have that Pokemon.

Here are the steps on how to catch Smeargle: 1) Defeat the Pokemon League and have access to the Battle Frontier. 2) Use Surf on the lake on the east side of the Battle Frontier. At the bottom of the waterfall, there should be a cave on the left side. 3) Enter the cave. Smeargle are the only Pokemon in the cave, so you are guaranteed to see one. 4) Smeargle isn't very hard to catch. 10 Ultra balls will probably do. Good luck!
