I just wonder... how many times I have to loose until I get enemies where I get about 50% winrate?

About 10-20% winrate so far.

All I get are enemies with perfect hands, golden and legendary enemies.

play a decent winrate deck and gitgud

Even though I finish legend every season almost, happens to me at the start of the season.

Legend players are starting to grind as well and even though they get ranks fast you still might face some tryhards with meta decks.

No use to try to have fun and win. Just use the best meta decks you can.

Git gud.

Just net deck.

Discard any fun and creativity and just net deck to beat other people with net decks.

too little information to give you any solid advice mate, all you gonna get with this is trolling

I'm going to assume you're serious.

Wait a week before you try ranking up in standard/wild.  All the hardcore guys will be diamond or legend already.

Copy a top five meta deck.  It might not be fun but you'll learn the deck eventually and rank up at the same time.
