I would take out the shards of gratitude and the feral bonds because, and I might be wrong, even with dexterity a deck with only flying weapons as creatures doesn't benefit enough from feral bonds and without mark of life SoGs aren't super helpful. Adrenastaves should have given enough healing. The deck might have needed more damage but I don't what you could add that wouldn't mess the deck up from the ai putting adrenaline on a creature instead of a flying staff. If you have them upgraded shards of freedom might have worked. This advice might not be the best advice that could be given but it should get your deck more wins then what it got.
