Why did I get tagged in Arena?

I was pretty sure that I got tagged in Arena as I could clearly see that the opponents’ decks were way too OP comparing to mine. I could hardly win more than 3 matches recently. Actually when I switched to my 2nd account, 4 or 5 wins were much easier. Just because I occasionally pressed retire button 1 or 2 time several months ago? Can any GMs check the history please?

When I mentioned 1 or 2, what was literally 1 or 2, not 3 or more!
