On occasion, unfortunately, despite the release of new cards, the dynamic of the game is more or less the same. Either you pray to RNGesus and enter the Arena, or play Constructed, where 95% of the decks you face will be exact copies of decks that the 'pros' have made. Which is made worse by the fact that so many cards are pretty much worthless, leaving certain deck types with very little in the way of customization. When new cards are released, or cards are altered, it takes very little time for the Meta to settle, with maybe 10 or less viable deck builds.
