This is general and about trade, so I'm putting it here.
Has Gamefreak implemented some safe way of doing trade evolutions? This was one of the things I hated the most since the original games. But back when it was done via link cable, it was somewhat safe because you would only do it with a friend, who would return your Pokémon afterwards.
Nowadays, however, we have the GTS. If you need a quick trade to evolve your Pokémon, and you have no available trustworthy people, what can you do? This is what's hindering me from buying the actual carts instead of a flashcart, because I love a lot of the Pokémon that evolve via trade, but trading with anyone you find runs a high risk of losing your Pokémon.
Also, do people still trade in 4th gen?
