Stonescar Sneak makes berserks brutal -_-'. It also makes reckless units steal threatening.
Ashara can attacks with almost everything (except an other Ashara or Stonescar Sneak).
I play manufacture instead of assembly line to avoid to flood the board and instantly die with any storm... Anyways, I generaly wont attacks with more than 2 units.
The rusty grenamotive can be weird but is an important tool. Stonescar Sneak activation is expensive. The rusty grenamotive generaly give enought power to activate it and play an unit. If the attack was with Ashara, it can also give the power to use a devour or combust to sacrify the unit before the end of the turn.
I play suffocate instead of torch. With quickdraw it's quite easy for the deck to deal with low HP units but it might be hard to deal with an Auralian marchant or equivalents... Overall the deck is weak against white decks that have got sandstorm titan, alhed, predatory carnosaur, etc... All those cards requiered several solutions, which obviously means card-desavantage. If you want better answers against that kind of deck you can add some annihilate (depend of the meta).
Have fun ;)
