We Oathbreaker now boys!
I am excited to see commander eligible Adventures this time around. This one seems like an amazing Adventure side with an okay creature. It feels like it pulls the deck in two different directions between being a good body to suit up, and having an anthem effect.
I have said something similar before.
Spoiler alert: people are not always up to co-op with you, so you may end up playing by yourself and not getting good use out of your dock
