If the fandom has not made at least one Utena joke by the end of this block someone needs to take away their permission to do anime references during Amonkhet
Oh shit, I'll admit to the obvious Utena references having completely slipped my mind. That makes building the vehicle deck even more appealing...
Meanwhile, I have put together a new Commander deck I've been meaning to do for a while with a lot of the GW stuff I've had sitting around
We actually had a guy in our group make a Sigarda deck that he unveiled just a couple of days ago. That deck didn't really tap her full potential, and I don't know that this one fully does either. There are a lot of very weak includes in here. Pretty much any vanilla in Commander is horrible no matter how on-theme it is, especially vanilla 1 and 2-drops. Doubly so in colors with slightly less-than-optimal draw power where a topdecked Elite Vanguard is a huge blow.
Maybe consider gradually cutting all of the vanillas, other creatures with small effects, and many of the auras for cards with slightly more Commander-relevant effects. Westvale Cult Leader, Increasing Devotion, Obelisk of Urd, Shamanic Revelation, and plenty of other cards are relatively cheap but will pack a lot more punch and you'll probably be much happier to draw them.
You're also extremely light on creature outside of a few Pacifisms, so even simple cards like Day of Judgment, Reprisal, and Divine Verdict will probably pull more than their weight.
Finally, you're missing a few of the inexpensive cards that I consider to be absolutely iron clad Commander stables including Cultivate, Kodama's Reach, and Temple of the False God. Find room for those if at all possible since they're nearly never not needed.
Edit: Actually I've never played a Commander deck with a curve that low, but 32 land would normally be considered brutally low. It might work since you've got a lot of cheap stuff, but that's not necessarily a good thing in Commander. Maybe consider cutting a lot of the small creatures for land (at least up to 36-37) and consider playing some of the mana-intensive card draw available in your colors like Tower of Fortunes, Loreseeker's Stone, Sandstone Oracle, and Mind's Eye. Finally, Mentor of the Meek is one of the best Humans in Commander so it might be worth hunting one of those down.
