With the arrival of the free expansion, Goblins vs Gnomes, Hearthstone: Heroes of Warcraft was given a new lease of life. The introduction of 123 new cards (from which can result another 20 items created by the circumstances of the battles), turned Hearthstone inside out. New mechanics, new decks, new tactics. We had to relearn how to play Hearthstone, but if you are still at the beginning of your addiction, look no further. Below you can get a good idea of the characteristics of the new cards and some examples of competitive decks for the new expansion, created by the best players of Hearthstone.
If you are familiar with the Warcraft universe, then you know that there are similarities between Gnomes and Goblins - in addition to their reduced height. The both have a passion for inventions. Most are great, but some have the potential to be magnificent - if they don't blow up in your face, that is. Translating that into the Hearthstone format, this means a new type of card - Mech.
As the name suggests, Mechs are a new type of mechanical minion, who benefit greatly from interaction with other Mechs. Some are stronger if others of its kind are in play, other lower the mana cost of the Mechs that follow after. Another element that distinguishes this type of minion is the Spare Part.
The Spare Parts are items that players can win after the fulfilment of certain conditions. The Clockwork Gnome, for example (below), offers a Spare Part to the player when he dies. These items cost one mana crystal and ensure various effects, from either adding +1 to the attack or defence of a minion, to granting the Provoke skill.
Not all new cards are Mechs. Each class received several unique cards, from spells to minions, that look to complement the different styles of play. Altogether there are eight new cards for each class, including a legendary. There are also several new neutral minions, and only a few are Mechs. This includes 11 neutral legendary minions.
The introduction of the new cards and game mechanics that come with them are naturally the big focus of the expansion, but there is another new feature that deserves to be mentioned - the Spectator mode. This way you can watch the matches of other players in your friends list. This is a good way to learn some new tactics.
The expansion brought various new combinations of cards and some impressive Decks. On the following pages you can find examples of Decks built by some of the best players of Hearthstone (and one of my own). These decks also include cards from the Curse of Naxxramas adventure. Try them and see if you can make them fit into your style. Good luck!
