The ShiftstonedEternal Power Calculator is a deck-building tool that visualizes your odds of drawing enough Influence and Power based specifically on the cards found in your deck.
Are you running 29 power just to tighten up consistency and 'abuse' the hand draw system? Off the cuff it feels backwards to add more power to an aggro deck to me.
Between recruit, cylix and nightfall you draw so many extra cards that a lot of the time you have to stay on the power curve to keep playing everything. In this format the wide board overwhelm them with units aggro feels worse than what this deck does, which is whittle them down in the first few turns with small units and then close with hellion or champion.
Calm Instructor with only 15 units it can pull seems a bit sus. Unless it's only purpose is to draw a unit, not caring if it plays it. Maybe your deck can absorb that kind of tempo loss. In any case, the original list has 23 units it can pull. I just ran the numbers, and your deck has about a 30% to whiff on a playable unit when Calm Instructor is played exactly on curve (and an 8% chance to completely whiff on any unit), depending on how many 1 or 2 cost units you drew in the first 10 cards. The original list has about a 13% chance to whiff on a playable unit (and a 4% chance to whiff on any unit). Just for comparison.
