Why not run Rootgrapple instead of Naturalize? It costs more, but the cost can be reduced by Bosk Banneret, and it's a cantrip so long as you have a Treefolk out. It can be tutored by a Treefolk Harbringer when you really need it, and it shoots down Planeswalkers, too. :)

I always chuckle when Talrand plays an unkicked Rite of Replication on his Archaeomancer, just to return the Rite of Replication back to his hand. Hehe. :)

I love how many different treefolk you have in here. I'll bet that keeps the deck interesting to play with. The only thing that jumps out at me is the Mighty Emergence. It doesn't look like you have that many treefolk that benefit from it. Although it does combo really well with Woodfall Primus, I'm not sure it's necessary.

You might consider running Acidic Slime for enchantment/artifact destruction instead of Naturalize. Naturalize is better for quickly tossing something that's causing trouble, and at instant speed, but the slime might fit the deck's theme better. It's an extra creature to boost your board presence. It has deathtouch which makes it likely to trade with a creature and allow your Skirsdag Priest to trigger. Your Llanowar Elves and Warden of the Wall help make the mana cost of 3GG manageable.

Well, the Tributes to Hunger and the Consuming Vapors will gain some life, but I agree, throwing in a Corrupt or something of the likes couldn't hurt.

I like the idea of a spirit deck in off-colours, and I have a real soft spot for Sekki, Season's Guide. :)

If you want to run with the Spirit theme a bit more:

You could consider Kodama of the South Tree in place of Overrun. The Kodama has a smaller version of the ability that will trigger on any spirit you play, or on your Kodama's Reach. You can repeat it with Glitterfang (also a Spirit), too.

You have a +1/+1 counter theme going on here too, it seems. You could throw in a Phantom Wurm, which would benefit from getting additional counters, and from Crowned Ceratok. Briarknit Kami is slower than the Ivy Lane Denizen, but is in the spirit theme, and triggers on spirits and arcane instead of on green creatures.

Scorched Rusalka can throw the 1/1 spirits you get from Sekki, the Zuberas, or the Honden at your opponent's face.

Primordial Sage is great to keep threats coming in your hand (it also works well with Glitterfang).

Iname, Life Aspect can pull dead Zuberas, Jugan, and Whatever spirits you've channeled back from your graveyard. Another channeling spirit to consider is Shinen of Life's Roar.

You could throw a Triskelion into your sideboard to get with Living Wish, he loves infinite counters. If you have your infinite combo ready when you get him out, though, it's an instant win if your opponents don't have an answer right away. Winning that way can be unfun, so beware.

You might consider Increasing Confusion. It's flashback can be a beast from mid- to late-game, and as a bonus it can still be used if you dump it into your graveyard with one of your other milling spells.

If you can't decide during a game if you would rather mill yourself or your opponents, (and you don't mind moving away from standard a smidge), you can mill everyone with Shared Trauma (and let others help), or Dreamborn Muse.

I like the theme and the title of your deck. :)

For bouncing back your own creatures, you could use Vedalken Mastermind. Temporal Adept has a similar ability, but with a pretty heavy cost, which might not be so bad if you build up a lot of mana, and you can use it to disrupt your opponents. Probably not as slick as the mastermind, but Temporal Adept fits the theme of your deck quite well.

A card I've always wanted to use that might fit in here (both in utility and theme) is Savor the Moment. It gives you an extra turn, which is in-theme, but it skips the untap step, so it ends up acting more as a blue Explore, which would help speed up your mana base. The extra upkeep step does mean it'll trigger your Trusted Advisor / Sunken Hope, though...

Dreamscape Artist is another option for mono-blue mana acceleration that you could try out. He's not fantastic, but he can do good things.

Wild Pair is a really fun card, and you've definitely found a way to show off it's power. It looks like most of your utility with the card is to find duplicates of creatures that you play. If you want to try further exploring the fun-factor of the card, try putting in groups of distinct creatures that can search for each other. All that matters is the sum of the power and toughness for creatures to match, so that gives you plenty of options, e.g. a Garruk's Packleader can search for a Thragtusk (4+4 = 5+3).

(Krosan Tusker at 6/5 can search for Verdeloth the Ancient at 4/7, as shown in the art.)

I'm curious about this oddball deck, so I'm just trying to figure out what exactly this deck does. So let me know if I'm getting any of this right. :)

It looks like your main win condition is Dovescape. All of your enchantment spells trigger it, and your Spheres of Safety and Dogged Hunters are there to answer the tokens your opponents might be making. You use the Lost Auramancers to fetch it, with some help from the Jhoira's Timebugs to pop them.

I see some synergy between Pure Reflection and Spirit Mirror. With the spirit mirror, you can shoot down whatever reflections your opponents make from the Pure Reflection, making the effect essentially one-sided (Dogged Hunter can shoot them down, too). But it doesn't look like you have that many creatures that benefit from the Pure Reflection. The biggest reflection you can get out is a 4/4 from the Lost Auramancers. I guess a 4/4 isn't anything your opponents can just ignore though, I guess.
