Looking for feedback.

Firstly. This deck is to play fast, getting creatures out and to buff them up with counters, mainly from Dragonscale General. Also the use of Crackling Doom + Harsh Sustenance + Lightning Strike linked with Satyr Firedancer to double the damage to opponent.

Secondly. This deck is to control the match, with Magma Spray + Wild Slash taking out the weaker early play creatures. Liliana Vess for control, Sorin, Solemn Visitor for life gain along with the tapped lands.

So what can be done to change and adapt or even improve?Please leave feedback!
