People always play decks, that work better than the others. That is why we see Skellige dominating the ladder. We used to see Nilfgard all over the place, and Consume Monsters before that... damn there was a time when people were salty about Control Radovid or sick thinning done by Scoia (Mercenary + BMC combo).
Frankly speaking I feel like it's a matter of days/weeks. CDPR will release yet another patch causing a meta shift... it's always like that. Meta decks are countered by decklist that becomes a new meta.
