Karmic Guide would be solid here, a 2/2 spirit with flying and pro black for five mana isn't bad, but when you cast it you get to bring a creature from your graveyard to the battlefield. That alone usually costs five mana. Plus it was in the Commander precons so I bet a lot of people have one in a binder.


Kira, Great Glass Spinnter- Flying 2/2 spirit for free is solid, but she also counters the first spell or ability of the turn that targets your creatures which is great protection. Granted it would hurt your Righteous Authority or Rogue's Gloves, but those are your only two auras or equipment, and I'd say it's worth the trade-off.


Keiga the Tide Star, 5/5 dragon spirit with flying that when it dies lets you take someone's creature.


Nikko-Onna- Enchantment removal is always useful, and in this case it's attached to a 2/2 body that you can return to your hand to re-use over and over if need be. This could be a star.


Bident of Thassa was such a huge bomb for you. Why not run two of them by using Coastal Piracy?
