Batterskull has been great, can come down early and can both grind AND is great vs aggro. Lots of value in using extra mana to equip it.
Shackles i haven't drawn a lot. It is supposed to help a bit vs tough creature matchups.
Sideboard is a bit all over the place, i put as many high impact stuff as i could. Torpor orb has been also good vs creature decks. Not sure about trading post because of stony but the value is real. Walker has been a great trinket mage target vs grixis shadow/non path midrange decks, highly recommend one.
I still love pests. They just win me so much games, i still like them better than the bird.
