Notable sideboard cards:

Kill shot/Mardu Banner x1 - banner was in the deck for the longest time before i just dropped it for kill shot in the third round.
Trumpet blast x1 - almost ran this, but decided to go with act of treason instead. Act of treason was the better card in probably all situations that I drew it.
Despise x2 - thought about running it vs slower decks, but I ended up never siding it in.
Bring Low x1 - Burn away for 1 mana more made me run that instead. no games I played would the difference in cost made a difference, and only one game where the difference in damage made a difference (I burned a 0/7 wall post combat)
Throttle x1 - thought about it, but never needed to run it.
Ainok Tracker x1 - brought it in when I thought 3/3 first strike would be better than vanilla 5/3. aka, 1 game.
