you can goto sam and dan games and buy unique codes and get a shiney mew from them. or shiney starters and things like that!

you have to use SnD coins
you cant get a mewtwo but you can get it if you trade
the codes are things that you can use to get prizes of a sort. if you want the code for the latest version, i would advise going on the Pokemon tower defence wiki, or just type in PDT wiki on google/bing. e.g. there was once a code for a regular mew, shiny missingno., and a celebi hat avatar. i hope this answers your question.
YES, ANY Pokemon can kill a mew. It all depends on how high your and the mews attack defence and health is. say the mew has low health and defence, it would be simple to take out.
There is no such pokemon as Mew-Three. But there is Mew and Mewtwo.
You need to go to the Nintendo event that has already passed, to get access to Mew. You need to catch mew, it is extremely rare to get a shiny mew. Another way is to simply use a Game shark or Action Replay code to encounter Shiny Pokemon
Only if you have a code breaker and the master code for ruby plus the mew and mewtwo code
sorry but "mew three" is not a real Pokemon
no
if you have Mew on a game boy Pokemon game migerate it to platinum and than go to the pal park.
the mew code for ruby is 71E09BD117FDFD02 and mewtwo is 30621E6F164FED85 these are the right once i think
