Originally inspired by a deck I saw Forsen playing the other week, this deck was a large factor in helping me get to legend for the first time - a goal that I had really been struggling with for months.
The deck makes use of the standard mech cards, in addition to Mana Wyrm and Unstable Portal which are just great Mage cards that help the deck often snowball out of control, more or less deciding the game by turn 4 or 5.
Another useful card that was recently released in LoE is the Gorillabot A-3, which I found really helpful at adjusting the deck to work well in different matchups. Discovering a Sneed's Old Shredder or a Piloted Sky Golem against a control deck could really swing things into my favour, while a Snowchugger or Annoy-o-Tron could buy me a few more turns vs face decks.
I feel this deck has the potential to contest almost any deck popular in the meta right now. From experience it seemed to do particularly well against all types of druid, while struggling a little bit against aggro shaman if I didn't get a good mulligan. More importantly, the deck does not fare too poorly vs secret paladin, which I feel like I come up against nearly every game. Sometimes I would keep Frostbolt in my opening hand if I didn't have another 2 drop so as to deal with a Secretkeeper or Knife Juggler and not get too far behind on board.
[EDIT 2] Getting over 40,000 views is insane, and far more than I ever expected on my first deck upload. I'm very thankful to everyone who upvoted or commented on the deck. I hope you all have fun climbing with the deck, and thanks again <3
