Maybe take a step back and a breather mate. I've played against it at multiple tournaments and it was an absolutely suffocating combo, to the point of making playing against it pointless with a lot of other armies.
The tenor of your post sounds very much like the comments I've seen here after the pre-release leaks, where everyone declared the Codex to be dead on arrival. And look how true that turned out to be.
Well perhaps you should look at my posting history, because I was one of those that argued that the Custodes codex was strong on arrival. Of course, now with those changes, we can go back to the default argument, and let me explain to you why.
Let's look at the first point.
Change the third bullet point of the Detachment Abilities of an Adeptus Custodes Detachment to read: ‘Troops units in Adeptus Custodes Detachments gain the Objective Secured ability (see the Warhammer 40,000 Core Book).
So automatically our Wardens, Terminators, Vexillas HQ's lose ObSec. Wardens were a staple in a few competitive lists, terminators not so much, but now after the bikes being reduced to worthlessness, they might actually see play. HQ's losing ObSec hurts somewhat, because there was nothing stopping you moving a SC on bike and nabbing a point. Now yes, we still do count as 2 models, but in an meta where tyranids, tau, Eldar (many T3 blobs of 5-20) are prevalent, this directly :cusss with our ability to score primary unless you run 10 x guard like in 8th edition. Seeing how you still will be running things in blobs of 3 models (so counts as 6 models) without obsec, and without CP changes (therefore incentivising us to still run in units of 3) how do you propose we score consistently on primary now?
Add the following to the Esteemed Amalgam, Emperor’s Auspice and Martial Discretion Stratagems: ‘You can only use this Stratagem once.
Alright off the bat let's start with Esteemed Amalgam. Emperor's chosen specific, change host. Surprisingly, this is a change I somewhat agree with, as this gets around the limitations of being locked into two solid shield hosts. Moving right along.
Emperor's Auspice - A change I disagree with strongly. As I pointed out before, this stratagem by itself didn't break the game in previous editions (arguably more imbalanced than this one) and was strong only because it was underpriced. A simple change to 2/3CP instead of 1/2CP would have fixed it, instead of making it once per game. Now we pop it once on a unit in a game, where it means close to nothing, because everything nowadays runs around with a large volume of shots with good strength, damage and AP. Now in a meta like that, you need something like this to prevent getting annihilated in this brain-dead meta. So you prevented a torrent of shots, from re-rolling, now let's deal with another blob doing the same thing in another turn. I.e. See Tau and Tyranids.
Martial Discretion - Honestly, I don't use it that much, so I'm neutral with this one.
Change the Adeptus Custodes keyword in all instances on the Arcane Genetic Alchemy and Emperor’s Auspice Stratagems to read, Adeptus Custodes Infantry.
Arcane Genetic Alchemy - oh boy, where do we begin with this mess. Same story with Emperor's Auspice, but minus the once per battle caveat. So Primaris units can get transhuman on them (such as ATV's and outriders) but our bikes can't? What did their assignment to the Vertus Praetors make them suddenly mechanised, and they suddenly forget they are flesh and bone just like the other Custodes? Oh wait, wait, we had that stratagem available in 8th edition for those 2CP earlier, and that didn't seem to break the game back when they had D6 weapons like every other faction..? And best of all, they even had ObSec then. So explain to me, how making this infantry only is logical when again, it's a simple matter of CP cost, instead of keywords.
In simple words: Transhuman/Auspice on bikes didn't break the game, it was only under-priced stratagems and the emperor's chosen shield host. So now can you see why I'm so angry? They didn't even address the things that made the Custodes strong properly, this honestly seems like a 15-30m write-up of them being too lazy to balance shield hosts/CP costs!
