@Soren841 This is a Standard deck, Baubles aren't legal. Also
Bone Saw is terrible.
On to the deck. It seems a bit all over the place. If you're trying to get out
Metalwork Colossus and Herald as fast as possible, you need to have 4 of each of them (to increase the chance that they'll be in your hand when you want to cast them) Also, they kind of want different things. Colossus wants a few big artifacts, like
Skysovereign, Consul Flagship,
Hedron Archive,
Cultivator's Caravan etc. so that they can come down early. Also if you are playing with Colossi,
Sanctum of Ugin is one of the best lands. When you cast a Colossus (ideally for free), you can sac all your Sanctums to find all the other Colossi in your deck (and also cast them for free!) I also like to end the chain with an
Elder Deep-Fiend, as a way to save the Colossi from
exile removal or push past a stalled board (when emerging from a Colossus, EDF only costs 2 blue)
Dinky creatures that aren't artifacts (like
Dhund Operative) don't really advance either the Colossus or Herald plans, so I think they are unnecessary.
So you need to focus more on what you want your deck to do.
Also
Prophetic Prism is one of the best artifacts for a Colossus deck. Also
Glint-Nest Crane is great. Also
Fling.
I'll leave my
Metalwork Colossus list here for reference, maybe it will help guide your process. (It has somewhat of a combo angle with
Paradox Engine/
Morbid Curiosity/
Aetherflux Reservoir, which is quite fun, but not the easiest to play)
