The economic in Pokemon slowly goes down. Many decent PvP Pokemon getting lower and lower cost because the market is full of them and the reason is because everyone who collect epic Pokemon for PvP or just for fun search for better. So this couse out date and make them hard for selling or even useless at some point. My suggestion is to be created NPC that can be called farmer Jack. His pourpusss will be to collect those Pokemons who are out of date in his farm and use them in his Pokemon reserve. In exchange for them he will be able to give you rare Candy's or other usable items which we usually buy. That will allow many players to clean thier PC, and maybe will help also to the new players to recover some cash or at least take back something if they get scammed from bought bad Pokemon. This idea is just a scratch for start and will like to hear more options not only from the players,but also from some moderator's 🙂
