Depends on what you mean. Cut is an HM, which allows you to teach it to every Pokemon you have that can learn it. The HM cut, has a limited amount of PP, so you can only use it a limited amount of times. And lastly, if you mean outside of battle, than there is no limit to how much you can use it - This example does not waste any PP according to my knowledge.
1. its SOUL SILVER and 2. yes you can you can buy it at a department store.

No, unless you have the AR (Action Replay). You can only see/catch it at Cerulean Cave.
No.Heart gold has a couple more Pokemon than soul silver
You can get more than one by matching all of the digits in the lottery.
There is a possibility that you can battle Groudon "more than once". If you save the game just before you battle Groudon, you can continually shut off the game and turn it back on for (technically) more than one chance to capture or defeat Groudon.
no, only evolving a magikarp it will be blue
No. Lugia is a legendary, which means there is only one of them.
Hopefully you have a warranty... It's more than likely broken
Yes, radio tower contest, by winning that.
HeartGold and SoulSilver are basically the same game with minor differences such as wild Pokemon and specific items.Most people say that soul silver is beter but i think heart gold because ho oh is more rarer than lugia since lugia is more popular
