College of Creation
Not quite Ainulindalë
Note of Potential
Your Bardic Inspiration gets more powerful, which is nice. Also, the Character with the inspiration uses their action economy to activate the powers.
Note of Destruction. A small PBAoE added to an attack (which can be a spell attack). It comes in nice but will taper off in the long run. It isn't a Smart AoE, so whomever is using it needs to mind their positioning, which might be a bother for someone locked in melee.
Note of Protection. Adds temp HP on a saving throw, provided you don't already have temp hp. A really weird rule restriction considering temp HP doesn't stack anyway.
Note of Inspiration. A free re-roll of your inspiration die. Not as good as advantage, but if you roll low to begin with, you don't have anything to lose.
Performance of Creation.
And yet again, nobody can create plate armor with their class ability. At worst, this looks like it could be used to swindle someone really nicely due to lasting for a minimum of 6 hours once you concentrate on it, but that's nothing new for PCs to be honest. Note that unlike the Fabricate spell, you don't have to know what you are making, nor do you need the raw materials for it. So you can make things like low-end Poisons, boats, or supplement the cost of a Revivify.
Animating Performance
After you have been fleecing the entire planet for 8 levels, and subsequently been banned from every market and black market by the combined efforts of the unified Merchants and Thieves guilds, you gain a more practical use for your Creation: A combat pet. And one of the new-style combat pets at that, uses your bonus action to attack for a decent amount of damage.
So right off the bat we have an action economy problem: It takes an action to create an item, and an action to maintain an items existence. Granted, this doesn't matter if you spend 10 min at the beginning of each day to make a pet, but it prevents the pet from being effectively summoned in combat. Also, as a bard with a souped up Bardic Inspiration, you want to spend your bonus actions to boost your party. It can also be used when you use your Bardic Inspiration, which is nice.
Thoughts:
I don't have any real complaints about this subclass other than the 14th level power, which comes out of nowhere and conflicts heavily with the action economy. And even then it's a minor nitpick. Though I am a bit worried that it will encourage a host of bards to go out in the world and commit fraud on every merchant they see.
Love Domain
What is love? (Baby don't hurt me)
Domain Spells.
Greater Restoration. That's a spell that implies some things~
Actually, most of the spell list is just implying things. Fortunately, the spells are generally useful as well.
Ceremony would be a good fit for this Domain, more so than Heroism anyway.
Emboldening Bond
This seems like it was left over from the Genie Warlock. Also it's a concentration free Bless (though it also stacks with Bless), which is powerful. Also you can expend a spell slot to get it back.
Channel Divinity: Impulsive Infatuation
So, you can willingly fail this saving throw. An interesting mechanic, mostly because it confirms that you cannot normally do so for most things. But ultimately, this will be used to trigger an OA, which your Rogue party member will legitimately love you for.
Protective Bond
Because Emboldening Bond wasn't good enough, this lets your lovebirds use their reactions to give resistance to all damage types to each other. Granted, a reaction is a premium price, but you will be glad to have the option.
Potent Spellcasting
Yes, this is not a melee cleric.
Enduring Unity
Unlimited range on your Bonds. Also can be used to turn anyone into a Paladin. Which is totally abusable. Imagine using your bond on the Party Fighter and their pet mouse, then keeping the mouse unconscious to give the Fighter advantage on all attacks and resistance to all damage for 60 seconds. It's an instant John Wick!
Thoughts:
I expect this domain to be popular. The capstone is great if you abuse it (though the power isn't out of line for a capstone, it can be triggered multiple times a day), but not so good if you use it as expected, because it ends the moment you heal the lover that got K.O.ed. A change that makes it works for the full duration once per lover per day would normalize the power and prevent the worst abuses of it.
Clockwork Soul
Domo arigato Mr Roboto.
Manifestations of Mechanus
One of the many contentious points I see on message boards is “Why do Sorcerers have to look weird?” Which is in direct conflict with the often toted idea that “Sorcerer are basically the X-men.” I mean, have you seen Beak?
Restore Balance
Finally, a power designed to capitalize on the rules interaction between Advantage and Disadvantage that isn't just “You ignore disadvantage.” It's really overdue. That said, it isn't exceptionally powerful (it's a tad bit less powerful than granting advantage would normally be), and this subclass doesn't get anything else until level 6 (unless you have an absolute need to be chrome). So level one still feels a bit under par.
Bulwark of Law
So you can spend some sorcery points to get a shield that stacks with Temp HP and Resistance, but it eats your reaction. At least it can be used on someone else. It's very passive, but I suppose that's fitting for a subclass powered by red tape.
Trance of Order
And now for something with teeth. You negate advantage on attacks rolls against you, and you can “take 10” on saving throws, attack rolls, and ability checks. Which include concentration checks. Also you can shout “I AM THE LAW” whenever you invoke it.
Clockwork Cavalcade
This is kind of underwhelming for a capstone. The big effects are repairing any object and dispelling level 5 (or below) magics. It just seems super situational for something that is supposed to be your ace in the hole.
Thoughts:
This subclass feels like it is lacking something at level 1. Maybe all it needs for that extra push is a list of bonus spells. And do something else with the capstone, like a reset button that turns back time a round or two, or something like that?
