Your deck is kind of all over the place. Saying it is more versatile is nice, but when that versatility comes at the cost of consistency what is the point? Although I have never played your deck I have played various bows. The hardest part is always the first few turns before you have really taken control. This deck will just find more games that it didn't draw that clutch Permafrost Shield, Bone Wall, SoGs, or needed to draw more than just one which is often the case. Seeing as it isn't unheard of for FGs to win before you can even set up a hourglass.
Beyond that there are a number of cards that confuse me. Epinephrine, what FG does that really help against? This is at its base a control deck, so winning a turn sooner will rarely matter, and using it as anti Bonewall, again winning a turn sooner, will rarely matter. Minor Phoenix, Fractal, and Imp Blessing also fit under these category for me too. Even if Imp Blessing can help grow an Otyugh having to wait for the single copy in such a large deck and getting it before you just throw the Oty on the field and Quint it.
You can even consider running multiple Permafrost Shields. Just in case one gets blown up, or stolen, or you need the Fire Buckler for some reason you can always throw down a new permafrost Shield again later. Best part though is the more you play the higher chance you will see it.
Good luck I really hope you can make it work!
