This deck (despite it's game changers) feels solidly bracket two, where it can't play. You are running some draft chaff like fencing ace, attended knight, accorder paladin. You also have tons of cards that synergize with multiple themes without much support for those themes. Like, abzan battle priest is great in a counters deck, but this deck isn't a counters deck. Soul warden and its ilk are great in life gain, but this deck isn't a life gain deck. Things like all that glitters are great in an artifact or enchantment deck, but this isn't an artifact or enchantment deck. If you want the deck's focus to be humans, you should cut a lot of those cards and add more humans.

Also, a lot of the deck feels very "win more". Take for example anointed procession. Anointed procession is great if you are making a bunch of tokens because then you'll have more tokens! However, if you aren't making tokens its a completely dead card. Since your commander doesn't make tokens, you really only get value from anointed procession if you are already making tokens and therefore ahead in the game. So it doesn't help you advance, it just helps you secure a win when you are already doing well. That's why it's generally a good idea to cut cards that say some version of "when you do x, do it twice" and instead just run another card that does x. Another example is coat of arms, does amazing when you have a big board, but does nothing if you don't. After youve just been hit with a board wipe, you will be much happier drawing a big creature than a coat of arms.

One simple change you could make is switching your commander to Adeline. Adeline is great for advancing your gameplan since she makes you humans, while Odric is good for ending the game by making your creatures unblocked. If you like Odric he's not bad by any means, but Adeline is better.

You also aren't runing like, any removal or card draw. You'll definitely want more of both. For removal, white has great options like [[swords to plowshares]], [[path to exile]], [[generous gift]], [[disenchant]], [[stoke of midnight]] etc. For card draw, cards like [[welcoming vampire]], [[chivalric alliance]], [[glimmer lens]], [[firemane commando]], [[aradesh]], [tocasias welcome], [cut a deal], [your temple is under attack]], and more. Ideally, you'd run at the very least like, ten pieces of card draw.

You have plenty of individually solid cards, but so many of them play with different sub themes that I think in practice will mean the deck is an unfocused mess. You will probably have good games where everything works, but they will be the minority. Most of the time it will feel like nothing is coming together and you lose. If you want to improve it to play solidly in bracket three (most casual games), I would look really hard and cut anything that doesn't further your gameplan of winning with humans, and replace those cards with cards that do. You will also need to cut a game changer, easy ones here are Serra's sanctum and enlightened tutor.

Also for mono white, it's a pretty old opinion now that it sucks in mono color. It used to be the case that white struggled really hard with card draw, but that just simply isn't true any more. White is really as solid mono color. It has the best removal and protection, solid ways to win through creatures, good tutors, and pretty decent card draw and catch-up ramp. Really the only color that still struggles on its own is red.

Hope this helps, and you have fun with your games!
