you can find by going to elite 4 in the cave
You can buy stone edge at the battle frontier TM stand.
Victory road B1f
there is no TM double edge
As far as I know, it's not a TM.
Yes with tm 71
It doesn't exist in the third generation.
buy many pokemon packets and hope you get lucky
The move Double Edge isn't available as a TM in Pokemon Leafgreen. Instead, head to the very end of Victory Road and talk to the person near the exit - he will tell you that you've worked very hard and you deserve to have one of your Pokemon learn Double Edge. It works just like a TM, but you can't carry it around with you - it's an in-game thing.
It cannot learn it by level, so the only way is by TM.
Basically you just have to beat all the tariners there.I would reccomend getting a pokemon with flash and kyurem if you are having trouble beating the trainers.As a reward you can find the item TM 71, which is stone edge!! :)
their is no tm for spark in pokemon
NOWHERE.The TM trick is not available as a TM in Pokemon Emerald
