Hey there. I'm new to these forums, so I really don't know if this is the correct place to ask for help. The thing is, I have been playing Pokemon Reborn for some time now, and I got to beat all the gym leaders. However after defeating the last one, on labradora arena, I cannot get out of the gym without beating Terra first. I did not expect that fight, and im literally stuck with only two revives, and two hyper potions. I'm literally locked in there and the only way possible of getting out is beating her. I cant even level up my pokemon from the pc due to not having the candies. However she is just too strong for my team. Most of her team one shots my pokemon with their attacks. I dont even know what to do. My stategy consists on beating Excadrill with wishiwashi (it resists but in low hp the earthquake). Use donphan with knock off to chansey (cuz her defense is too high with the item) and then blaziken finishes the job. But after this, the porygon, the garchomp, and the quagsire just sweeps. Like, I tried to use whismicot with whirpool to go faster, but her garchomp is still too fast. At least I can use toxic with scolipide on some of them. All the other viable pokemon I have are those too. I cant do anything anymore. Cant get out, and I dont even have money to buy if I could. Could someone of you lend me a hand and trade with me some Pokemon that could sweep her team? Its just this damn battle. I can trade it back once Im finished with this.
