Task List/trade lv5
You have a lot of patience. Trade or gift 1250 Pokémon - the hoarders must be very happy. You could find someone to help you trade your Pokémon back and forth, giving both you and your trading partner a headache. Trading valuable Pokémon/items through the trading forums can also help.
You get a Pokémon, and you get a Pokémon, and everyone gets a Pokémon!
