Hearthpwn

I play a lot for fun, this deck is a simple rogue deck with some of the Mech cards I had left over after disenchanting a lot of cards.

But if you swap the Shiv for Eviscerate. And the Assassinate for Tinker's Sharpsword Oil.

Doing this will make the deck a lot faster and make the Sprint useless. So I would swap it back down for a Assassin's Blade you want at-least one when playing with Tinker's Sharpsword Oil.

If you do this you should have a lot of fun in Ranked with this deck.

But remember your only draw card cost 3 mana Fan of Knives for 1 card. but there are always spare parts you are picking up they only cost 1 but can be invaluable.

I hope this answered your question, indirectly.
Good luck in ranked and have fun.

let me know how you get on.
