The decks and the loops that you mention are truly unfocused though, and the assembly of the combos feels coincidental.
What? Are you calling the partner commanders and Alela "truly unfocused?" I also didn't mention any alternate loops. I'm confused again, so I'm just going to make suggestions.
I was saying that partner combos or Alela would be better because Sydri doesn't really offer anything. You usually don't want your artifacts to be creatures, and giving them
lifelink and deathtouch is practically useless.
Partner combos like
Silas Renn, Seeker Adept and
Rebbec, Architect of Ascension would protect combo pieces, give you recursion, and still allow esper combo routes like Urza Foundry (or just use KCI, since you're already running it).
Alela keeps you in esper and turns all of your artifacts into faeries which can chump block or get sacrificed to an
Ashnod's Altar or another engine to generate fast value.
As for combos, I would include more routes for infinite mana and outlets that are useful outside of combo turn. You're running five mana rocks and all of your tutors are only for artifacts, not to mention no counters. It might be easy for your opponents to
disrupt your combo.
Outlets like
Memnarch can be used in the midgame to
disrupt your opponents and win with infinite mana,
Blue Sun's Zenith can draw cards or deck an opponent, and something like
Lux Cannon can provide repeated removal while winning the game with infinite untaps.
