Got to to Legend 28 by mostly playing this deck.
first of all thanks for the positive feedback so far. This guide is just going to focus on the tech decisions and explains the general game strategy.
Basically this is a standard Midrange Hunter Deck just with more aggressive techcards. So your game strategy is to control the board early to midgame, until you can outrace your opponent with your Hero Power, the board you build up and direct Damage spells.
This deck does really well against all sorts of Aggro and Midrangedecks, but has a hard time against Controldecks like Renolock or Controlpriest.
Why Leper Gnome?
Leper Gnome can trade with a lot of 2 drops like Dark Peddler or Knife Juggler and when uncontested gives you nice face damage (+the dmg of the death rattle). And with its death rattle, Leper Gnome is also able to deal face dmg through taunts, which might come in handy.
Why 1 Webspinner?
Why Explosive Trap?
I think its really good against decks that flood the board. Also running 2 copys of it is kinda necessary to make sure that you draw a copy or get one out of Mad Scientist. It also stops the Druidcombo and often wins you the game if you play it before their turn 9. Furthermore people dont expect Explosive Traps in Midrange Hunter, so they often just go for face thinking it isFreezing Trap or Snake Trap.
They really depent on what class you are facing and have been explained in several other Midrange Hunter Guides.
Thanks to Khristophesaurus for the Gameplay Video.
Deck works way better on ladder than any of the other midrange hunters currently around. I probably write a more detailed guide if this gets enough upvotes, but mulligan and general strategy is basically the standard of midrange hunter.
