Firstly, congrats on your first Deck Post, it can be daunting to throw your ideas out to the community, hope you find help constructive
I'll reply to this trying to keep as many of your chosen cards and theme as possible, though it's always going to a be a clunky strategy.
The biggest thing you need to do is get it down to 30 cards. The fewer cards you have, the better your chances for balanced draws, and as you have a max of 6 Animate Weapons, this is a MUST for your deck. So lets have a look at what can go
As it's a SN rainbow, and even though you have an entropy mark, all the entropy cards from your SoSes will need your entropy quanta.
-Diss Shield.
-Lycan.
The mark can power the discord and SoSes, so
-entropy pen x2.
A single Shard of Void does literally nothing for you, as you will be doing more damage than it's max health cut. this MUST go. The Steam Machine sadly costs too much to run in a SNBow like this, so:
-Steam Machine
-SoV
Fate Egg is a fun card, I understand why you want it, but for this deck you want to be getting your combos ASAP, so it will be much MUCH better if you can get some HourGlasses in here. I would say
-Fate Egg
+2x Hourglass
That single Phase shield is a preference, keep it if you like, but on it's own it's a bit useless. Consider the fact that you can only have 6 flying weapons, but you can ALSO have one in your weapon slot. Why not have a Lobotomiser? gives you an extra powerful weapon effect. If you are missing the rare, then a Twin Universe also gives you an extra flying weapon.
-Phase Shield
+Lobo/TU
Now it gets tricky, this is how the deck looks now.

Much better. Still not 30 cards though.
From here it gets difficult. This deck idea is tough to implement because weapons are generally support cards, and you are needing 2 cards (weapon+AW) for each of your attacking creatures, so after a bit of testing, I see why you have the 4 "growth" creatures in there. The 2 Hourglasses help a LOT in getting through your deck, so if you want to play it like this it it should work ok.
The other option 2 options are
a) Focus entirely on your SoSe Flying Weapons. -Lava Golem -FFQ -Forest Spectre and then you can -1 Quantum Tower:

b) Sacrifice the SoSes to keep more damage and have a better chance of out-rushing your opponents:

Personally, I would drop the SoSes. SoSes are GREAT, but they take up space in a rainbow, and because your rainbow relies on a combo, you need all the space you can get, and it's a bit too slow without the growth creatures.
Hope this helped, I look forward to seeing other decks you want help with
EDIT: After a few games testing, the Deck without the SoSes is actually pretty decent, I'd use that one if I were you. If you want a SoSe bow, make it but i dont think it fits with a combo deck like this
