Based on @DUO's Smoke and Ash, modified for cards I have and play style I wanted.

Druid is OP, and Drums / Sir Agravaine / Water sites can be removed if you want to run Seer / Sorcerer which is also good (but not as good).

Going 2nd is preferable to get more value out of early imps / kobolds.

Mana goal is 6 sites, and or Ruby core, so we can play infernal legion as soon as we can. I like to draw a site on turn 2 or 3 if my hand supports it.

Trinket works great on the kobolds as you get to choose the order of events so trinket can add to the end of turn free strike before returning to hand.

Infernal legion is the main damage workhorse
