pretty basic backspace rogue
I wouldn't run defias in this. annoyotron or horseriders would fit the slot nicely... maybe even horseriders over the arcane golems to combo with the coldbloods as spot removal.
Its a pretty tough deck to play.. its very agressive. im not sure about double oil in the list either. double owl seems overkill also..

I can't stand hearthpwn lists.. But its hard to find inspiration for a list like this on the ladder, because it is so uncommon.. Your best bet is to adjust to your playstyle//meta, and not play a list directly off hearthpwn.. At least not something as uncommon as backspace.. the lists posted are always a bit wonky.

What do you guys suggest for someone who's pretty new like me?
The only Hero's I do not like are Hunter and Warrior.

Got any example decks?

Hunter is good.. Mid range hunter.. Warrior is usually way to expensive of a deck to run with much success

i'd suggest you to buy some gvg packs and play mech decks because they can be played with most of the classes with excellent results

I hardly played any rogue games myself, but that deck is fun to play and I recommend trying it if you got the cards (it mostly needs a few Naxx wings and 2 League of Explorers wings).

I do not have Leeroy Jenkins myself and use an Arcane Golem instead. The next step down would be another charge minion like wolf rider or argent horserider. A nightblade might work, too.

There is a Dr. Boom in this deck, but a shadowstep or defias ringleader (or stormwind / muklas champion?) should be fine at lower ranks.

If he is to buy any thing the adventures are most important .. And classic packs will get him most success

Of course you need the gold.

How to get a lot of dust ? It's easy really.. just buy packs with money.

Not saying Troll did that, but it's pretty simple.

People have been playing for a couple years now. They also have cash to buy cards to dust just stacks

Naxxramus is the absolute most important thing
