I really want the storm deck to work. I might tune down some strategies and add interaction after more playtesting.
The fastbond deck is powerful and fun, but it makes for a bad drafting experience because there is very little competition for the green cards in other archetypes. Instead, I'm experimenting with more combo pieces in Thassa's Oracle and Laboratory Maniac with Doomsday, Hermit Druid, and Demonic Consultation, some more powerful and splashable interaction in Grist, fun broken cards to play with flash, and a storm win condition with Mind's Desire. After this change, I'm interested in observing play patterns with orcish bowmasters.
I've been reluctant to include a hullbreacher or narset effect, but bowmasters gives opponents agency to play against it in more interesting ways.
Emry is versatile and supports reanmiator, tinker, painter, and welder decks.
Future changes to consider include Aether Spellbomb to go with Urza's Saga and Emry if more interaction is needed against creature cheating strategies. Tainted Pact goes well with labman and thoracle if they need support. I may also be interested in ignite memories or thousand year storm to help the storm deck.
Trying more castable cards that overlap in good colors for sneak attack/show and tell/reanimator, plus chaos defiler for a welder engine. Trying out the one ring for its high power level as a card advantage engine.
Considering in the next revision to add mishra's workshop
There were simply too many mana rocks. Adding doubles of the Grixis duals to ease the demand for them. Coalition Relic for more flexible splashing / ramp. City of Traitors over Library because Library is barely playable. Prismatic Ending over March for the flexibility.
Side-grade Noble for Green Sun, which still goes well with Dryad Arbor, Ignoble, and Birds of Paradise. Green Sun plays better with the Fastbond deck as a win condition or tutor for a combo piece creature.
Exhume for more redundancy in Reanimator.
Some changes to support Show and Tell and Natural Order. I want to add Atraxa, and I like Dryad Arbor as a simple way to support Natural Order. Splinter Twin combo is out in favor of the more synergistic Painter's Servant + Grindstone combo that fits in the existing Goblin Welder and Goblin Engineer decks. I am seriously considering the addition of Green Sun's Zenith, possibly over noble hierarch.

Remove duplicates from bugged replacement
Adding a key for the time vault player to get a second shot at it.
Replacing Mightstone and Weakstone with Coveted Jewel which plays better with PO.
