Trading Items
Looks like you can trade items by giving it to a Pokémon to hold in the game. Apologies if I am being Mr. Obvious, but it gets me more hyped.
Would love to see giving a Metal Coat to Scyther and sending it over to a friend and watch it evolve into a Scizor!
Or an Onix into Steelix! (Really hoping the multiplier is good here)
