My understanding is that only the masterball has any substantial prospects of success in catching legendary birds and MewTwo. In the game I played you could only get one masterball in the whole game (but on the plus side you had a 100% chance of catching whatever you throw it at) assuming you don't exploit the Missingo glitch. Weakening it to the point where it only had a few hit point then throwing ultraballs at it en mass was doable but really hard since you had to get it to the edge of fainting but if you made it faint it was all over and you wouldn't get another chance (well you would if you reloaded the game :P). Anything less than an ultraball was impossible from what I understand.
