get a bunch of Pokemon lv 50 and above
take a weak pokemon to the elite four
Take them to the elite 4 and battle there.
If you already beat the game, just battling the Elite Four is a great way if you can take the repetition!
it really depends on the move sets. you can't change pokemon, so you should have a variety of moves, especially fire, flying, psychic, and dragon. however, it was recently researched that a level 5 rattata could take the whole elite four down, using various tms but also starter moves.right...(hint sarcasm)
The high 40's, but if you want to be safe, get them in the 50's. Make sure they all know strong moves. You will definitely need a level 50 dragon type, to take care of the champion. Good luck!
Train your Pokemon up to level 65 then take them on
Give it an EXP Share and take 5 other strong pokemon. Then go through the Elite Four. I can guaratee that it will be at least Level 20 when you finish.What I usually do is take my strongest Pokemon and go to a route with high level Pokemon, and put the level 1 in the first slot. When you get into a battle, immediately switch to the stronger Pokemon and battle. The level 1 will gain experience extremely quickly.
When 6 of your best Pokemon reach to at least level 70, keep beating the Elite Four. This way is very easy. If you don't want to hack, there is no way of getting free money in Pokemon. You have to take time in training your Pokemon to beat the Elite Four.
You must defeat the Elite Four and Steven first. Once you've done this, fly to Mosdeep City, then go into the house towards the north-west of the city that has no people in it. There should be a Pokeball there and a note from Steven saying that he left the Pokemon inside for you, which is a level 5 Beldum. At level 20 it evolves into Metang, and then at level 45 Metang evolves into Metagross. After beating the Elite Four, head to Steven's house in Mossdeep. In there, take the pokeball. The Pokeball will give you Beldum, which you will have to level up to Metagross
yes, you can.... it will take forever though.....
give beautifly exp share and take him/her to the elite four and train there.
It depends on what level your Pokemon is at if low it should be quicker if high should be longer
