She sounds like a really good addition. Defense and evasion make her a tough target to deal with. With Exalted, she's gonna be such a pain. Maybe only as a two of though.
Parallel Lives could be of great use here. Fungal Sprouting is only going to give you two tokens most of the time which is not going to be worth 4 mana when you could just use Lingering Souls instead. I think Intangible Virtue would be also a great boost to the deck.
It's a nice cantrip that creates disruption. Useful against opponents trying to set themselves up with Ponder and with any luck, it throws any cards they're trying to get into the graveyard before they can play them. It's also nice to draw a card for just one mana too.
With Tamiyo's ultimate, you can thought scour yourself, allowing you to draw three cards.
What's the Restoration Angel for? I'm really surprised to only see one sword in both the MB and SB combined too. 19 lands seems really minimal. Without Ponder this most likely wouldn't work though.
I feel like we should have ten 1 drops in here at least and I'm kind of wanting to get some testing in with Angel of jubliation I'm not quite sold on the paladin as for the most part I see him as a vanilla 2/2 for 3 which is a clogged slot in the deck. His ability is nice, but how many times is he going to be a terrible top deck.
What one drops do we have other than Champion and Traveler? I tried Elite Vanguard once. Not that great.
Pretty standard, but if you're running 3 Thalia, Guardian of Thraben you probably don't want to be paying 4 mana for Oblivion Ring. For 4 mana, you should be throwing down that Hero of Bladehold and letting it take care of any problems you might be having. Your Fiend Hunters and Leonin Relic-Warders should do just fine for removal anyway. I would sideboard one Thalia and take out the O-Rings to put in three or four GtTs.
A U/R Jace would be pretty cool to see though.
Just to make sure, if I had four Akrasan Squires on the field and one attacks by itself, it would get +4/+4?

Why has no one regarded this as one of the best posts on the forum ever?
However, back on topic, I think this is a pretty good replacement for Ponder. Still works for Delver but it doesn't give you crazy advantage.
If not, Opt is a good idea just because it doesn't introduce a new keyword like Preordain.
