Pokemon explore of time....i need HELLLPPPP!!!!!!?

This may not be the best answer but you could buy an action replay and cheat. they are so worth the money. if not try a whirlpool, toxic combo then use allot of orin berries. do smaller jobs till toxic is available. have a partner learn it and let him faint after he poisons him. I know you don't want to go through the hiden land again so leave out the poison.
