Not-generated in games itens

[tonytera14]

Hello!

Since i've started playing pokémon in switch, i've noticed that some pokémon come in trades with different and rare itens. 

And then I've started using pkhex to build some pokémon or acess old events as well. 

But i've got a question: If I get a rare iten (like a master) by trading with others or if i send the iten with a pokémon i've made myself... If I use that iten (that i've receveid or sent to the game), the pokémon i will catch will be considered legal/legit, considering that the iten was not generated in the real game?

Held items are just 2 bytes of data, and your inventory is nothing more than a count of specific items.

Hacked items are not "traceable" besides unbelievable counts (who farms more than a dozen master balls?) or impossible to obtain items.
