Saving your Masterball for no reason

Anyone here ever just keep their Master ball, and never use it? Even when completing your Pokédex?
Mewtwo was rather easy catching with a Ultra ball. All I did was freeze him, and presto! He was mine >:D
I tend to always save my masterball, and never use it. Keep it as a memento, on how I could've easily done something. Fighting for what you want, though, is always the better choice for me.
What about you? Do you like keeping your Masterball safe and sound?

I used my Masterball on Kyurem, was too tired and lazy to fight. I usually save them for the occasional wild shiny. :P

I don't use master ball unless its for a shiny, especially when my Pokemon are too strong for the shiny, and if I attack it, it might faint in one hit (exactly what I did with my shiny Mienfoo).

I never use my masterball since I know it'll be possible to catch any Pokemon, the only reason I'd use it if I was in a certain situation that was mentioned before (Shiny Pokemon that could get away). The only 'normal' Pokemon I'd use it on is Mewtwo, it suits that Pokemon very well and reminds me of the Manga.

I save my Master Ball, not just for nothing, but for that special once-in-a-lifetime or precioussss shiny Pokemon that might escape my clutches by Explosion or Self-Destruct. The Master Ball is reserved for only that purpose and that purpose only. Legendary Pokemon can be caught with normal Ultra or Dusk Balls; it does not need that ultimate capture rate. Where's the challenge in that?

I never use it, saving it for the rather unlikely case that say I see a shiny that could run off/kill itself. After all if I can catch the legendaries with a bit of effort then it doesn't seem too necessary to use up the one master ball on one of them to me. Plus it feels more worth it than just starting the battle and catching it a moment later. How else will I get angry while nice music plays? =p

Even though I've yet to do it, I usually save my master ball for a soft reset legendary. Other than that, I'd never use it unless, I had no other poke balls to catch a random shiny(which rarely happens).

I saved it once in a plathrough of pokemon Firered. Normally I would use it on a roamer or a shiny.

I usually catch the legendaries with Ultra Balls, even if some seem to take forever...
The Master Ball i've always saved up for the day i finally encounter a shiny...which has never been the case

i catch all my legendaries with normal pokeballs so the masterball has really never been important to me. i have like, four sitting around on my black 2. 2 from in game, 1 from black, and 1 from the lottery. i've tried trading legendaries holding them for shinies but it rarely works. now i just keep hold of them in case i run into a self destructing shiny.

Thanks for the responses guys. Its nice to see how many people don't... "cheat" and save the masterball.

I think in the past few years, I've only ever used a Masterball once, and that was on a ROM hack with a Dark Lugia only catchable with a Mastarball, so kind of justified, there...

Using the Masterball in general just makes the whole thing kind of anti-climactic, I find. A battle that's meant to be a definitive part of the game, over pretty much as soon as it begins. Just doesn't seem right, really. Imagine going into facing the Pokémon League champion, only to find after this whole build-up that they are armed only with a level three Magikarp, or something... Except it isn't anywhere near as funny as that would be. Buzzkill.

Just like quite a few others have said, I've always saved up my Master Ball for a shiny Pokemon, just so I could nab it right away without any worries (so far all I've gotten is a Shiny Ducklett). Other than that, I just use something like a Dusk Ball on legendaries, since they're pretty easy to get as long as you have some patience.

I often save up my Master Ball for a Legendary that I know will be troublesome to catch, like when I used it on Kyurem in Black 2.

Since I almost always never find a shiny most of the time I don't usually save it for them.

I usually use them for a roamer, but if I have no intentions of catching the roamer of the game, I just trade the Master Ball over to my storage game when I trade in my team. Nice to have them in the case of a random shiny and you're ridiculous over or under leveled or something.

I never use the Masterball. I just keep saving it.... "just in case". In case of what, I can't imagine. I just feel like I would rather have the option to use it than not have the option, even if I never use that option.

This is also a bad habit that applies to my normal life haha.

Usually save it for a roamer or a really rare shiny encounter.

Yes - I pretty much save it for no reason.
I guess it's in case I....
No - it's really for no particular reason. I don't deliberately not use it or anything like that - I catch whatever I catch in whatever I catch it in. I just can't quite bring myself to use the one and only Masterball, just because if I use it, it won't be there if I want to use it.
