The meta has been shifting in Hearthstone which is predictable after the release of a new set. GVG is shaking things up just like Blizzard wanted.
So what are some of the biggest new decks? Well, Mech Mage is one of them.
The expansion came with plenty of new minions to flood the board early such as Clockwork Gnome, Mechwarper, Micro Machine, and Snowchugger for Mages.

For the mid game there’s Piloted Shredder, Madder Bomber, Bomb Lobber, and Goblin Blastmage. Each of them brings a decent body of their own along with an ability that will usually trade with an opponent’s minion while still leaving your minion alive, either through a damaging battlecry or the Shredder‘s deathrattle.

Add in the normal strong spells of a Mage and the deck is quite solid. What makes it devastating is the new Spare Parts cards. They’re cheap and the deck has Clockwork Gnome, Tinkertown Technician, and Mechanical Yeti to create them.

The cheapness is wonderful. They can activate Mana Wyrm to pump it up. They can activate Gadgetzan to draw cards. They can activate Antonidas to create three Fireballs on the turn you drop him. They also work with the new legendary, Gazlowe, to create tons of mechs for you to play.
Mage also got a new toy with the epic spell, Echo of Medivh. The spell is used in the old Freeze Mage Giant deck which focused on freezing out their opponent and drawing cards until they could play giants and Duplicate them. Well now you can duplicate them another way!

Say you’re at 10 life. You feel safe because you’ve got two Molten Giants that you gave taunt to on the board and you have an Ice Block secret. Now throw in Echo of Medivh and suddenly you have two spares of one of the most powerful minions in the game! Day9 has a video where he fills his board with 6 Molten Giants in one turn using this trick.
The deathrattle aggro decks that Warlock, Priest, and Hunter run all got some improvements with Clockwork Gnome and the Piloted cards. Mechwarper and Micro Machine also help out with mech aggro decks.
Ramp Druid got some new tools. Grove Tender helps them ramp up faster while also providing a body. Tree of Life allows a full reset of life when you’re facing an aggro deck.
Handlock got Mal’Ganis, so now your opponents can’t even rush you down if you drop that. Fortunately, some cards were added to counter Handlock and any other oppressive control matchup. Goblin Sapper and Clockwork Giant are perfect against decks that like to stock up on lots of cards.
There are tons of other cool cards that have slightly altered existing deck. Shrinkmeister and Voljin for Priest. Muster for Battle, Quartermaster, and Bolvar Fordragon for Paladin. Gahz’rilla for Hunter. A slight Murloc focus for Shaman along with Crackle for burst based decks. Rogue got some awesome new mech cards along with the means to possibly create a viable pirate deck. I haven’t seen one yet, but I’ll bet its coming.
So lots of new cards to try out! I’ve only just now finished spending out all my gold on Arena runs to learn the new cards in that mode. Now I have to see how what I have works in Ranked. I just got a Mal’Ganis for a Demonlock deck in my last Arena run. Maybe I’ll give that a try!
