Avid Hearthstone players will already know that Blizzard has already announced the latest expansion to Hearthstone in the form of The Grand Tournament. Aside from new cards and new features, there are expected to be some new mechanics. Blizzard announced as much during its Gamescom media briefing.
Blizzard says that the new mechanic is called “Reveal” and what it does is allow players to take a sneak peek at the next card in their opponent’s deck. That could come in very handy. It will allow you to make decisions ahead of time and be better prepared for what’s coming. The mechanic is shown off in a card called Master Jouster.
The card reveals the top cards from both your deck and your opponent’s. If the card revealed in your deck costs more to cast than your opponent’s Master Jouster will gain an additional +1 durability, making it a 2/3 creature. If not then nothing happens and your card remains the same, except that both you and your opponent know what’s coming next. This should add a bit more depth to the game.
There will probably be other cards that take advantage of this new mechanic, but for now Master Jouster is the one we know about. We don’t know when The Grand Tournament will be launched, but players are more than ready.
