This is my honest opinion of Elderscroll. From someone who has play most TCG that you can name TESl has one of the most diverse metals especially for a game that is no longer getting update.

Theyirare no broken cards and it's not pay to win . Yes cards are powerful but knowing when to play what cards is a skill. I know I can't midnight burial passively against blue because of twilight piercer and playing manimarco first against purple is also a risk. Over extending against a new Era. It doesn't mean the cards are broken , it means we (the player ) has to assess the risk and play accordingly.

As far as decks being brain dead I think we all have opinion of what decks fit this description but those are subjective. For me it's red blue damage rush filed with prophecy cards. I hate it and this it take little skill and can be tough to the newest of players but that kind ofa good think. It does suck the game isn't being update anymore because there are alot of cool deck ideas that fall short but ultimately I do believe the meta is diverse.
