So the reason i am making this suggestion is because i am quite tired of always meeting those same decks that are META this week, like feisty fish deck or Mega Math, i can also use those decks but it makes the game more boring because it is too repetitive to use them, i have seen some other suggestions like nerf those meta decks, but in my personal opinion, why not just add a ban feature for specific cards from those decks? for example ban electric eel and mobius strip cards for this week's rank, this will make those deck still playable but not as strong as before and more counterable by other decks. and for the next week maybe ban one of the cards that is too strong for that week like loki for low energy week. this will make players have to find 
other replacements so that the decks in the rank will be more varied each week.
Thanks for hearing me, also sorry for my bad english, its not my 1st language hehe
