How did Pokemon get the gold crown? What's the use?

In Yuan Qing Square, "Treasure Hunting in Lottery House ★5" won the first prize. This is fucking crazy. Apart from the lottery, five-star facilities are disgusting enough.

What's the use of Pokemon's golden crown?

An elf of 100, specially trained to 6v.

Consumables, once used up, are gone.

The lottery house can get the same property as the black and white 2 Join Avenue lottery house, and the level of the lottery house is improved and the prizes are better.
