This is great man, thank you! Exactly what I was looking for. Glad I finally remembered my old username.

Energy Field is another decent card to consider, as it combos nicely with Wheel of Sun and Moon.

So do you use stuff like Gridlock and Glimpse the Sun God to target your own guys? Would that happen right before your untap phase?

I've always wanted to try Lightning Serpent in a red Tron deck.

Another card I'd recommend that doesn't see much play is Thieves' Fortune. It's amazing if you're running Rogues, which you have two of right now.

Two of the weakest cards I see (although they fit your strategy) are Hunt the Weak and Implement of Ferocity. The other I would question, though not a bad card by any means, is Traverse the Ulvenwald. Do you achieve Delirium that often? Do you hold them in your hand until you do, so you can grab a creature? If you mostly end up using them to fetch a land, that slot would also be flexible (to me), since Cryptolith Rite should be giving you all the mana accel you need. That being said, I still like Rishkar in these decks. Even though you probably won't need the extra mana, he facilitates +1/+1 counter triggers, and turn 1 Module, turn 2 Mimic (on Servo), turn 3 Rishkar is a REALLY strong series of early plays for this deck. Acting as a pseudo-combo, they provide a token for each 1 mana you spend. I would consider adding 2 copies back in. I would also consider leaving Ajani as a singleton (maybe even cut altogether), if you need to free up an extra slot.

SO, all that would leave us with:
-1 Hunt the Weak
-1 Ajani
-1 Implement of Ferocity
-2 Traverse (tenative, depending on how you use it)
+2 Rishkar
+3 Hidden Stockpile

Don't forget that Stockpile's scry ability will help you repeatedly filter your deck, too. Traverse seems even less necessary if you go this route. Again, these are just some suggestions. Feel free to take it whatever direction you choose. This is definitely a fun deck to play, as there are a boatload of interactions.

A single Urborg would work to turn all your Urza lands into swamps and is searchable with Expedition Map, as well.

Have you considered the Urzatron lands with Expedition Map? Would help keep it two colors.

Metallic Mimic set to "Servo" is a fun trick for Animation Module decks. There's also Hidden Stockpile to consider.

I actually recently changed my list from Legacy to Modern, so it should look familiar. As I said, you inspired the changes, so Spellskite was a recent addition. Main difference is no Inspector/Fatal Push combo, just Path and O-Ring, and with Leveler. The deck felt (to me) like it needed one more big beater. I'm definitely still looking for suggestions, namely a replacement for Night's Whisper.

You've inspired me to make my version Modern playable! One additional resource that I've been using - Sundial of the Infinite. In a pinch, you can use its ability to end the turn with one of the negative ETB abilities on the stack. I use four Hushwing, four Orb and two Sundial. I really like the inclusion of Yahenni's Expertise, though. I may have to find space for that.

How about Shrapnel Blast?

One-sided board wipes FTW! So satisfying. Love the spirits, but one other thing that works really well as an alternative finisher/beater: Yavimaya Enchantress + Rancor. Often swings for ridiculous amounts of trampling damage.

IDK what your budget is like, but I enjoy cheating EE into play turn three with Academy Rector.

I realize this deck is a little older, but I love Tamanoa/Soulfire decks! One thing you gotta try is Searing Meditation or Pyrohemia. I'd suggest -1 Molten Vortex, -1 Ajani, then +2 either of those. They both work so well, I think you'll really like them.

Enchanted Evening into Primeval Light is one of my all-time favorite plays in all of MTG. Nice build.

You don't like plain ol' Pariah?

Not sure if you're budget oriented or not, but this deck is begging for at least a couple Timber Protectors. Also consider Rootgrapple over Beast Within, as it's able to be searched for with Harbinger and have it's cost reduced by Banneret. But mostly for the tribal flavor.

Love Treefolk! I think -2 Rampant Growth, +2 Explore would help.

Nice build! Always wanted to make something out of Bombshell. The only thing I could suggest is maybe something to help keep Trader alive? Swiftfoot Boots and Lightning Greaves come to mind. Vexing Devil might be tricky with Fling and combined with stuff like Dash Hopes.

Something like Vile Redeemer or Void Attendant might be worth consideration. Although, Attendant may need a couple Transgress the Mind or something to be effective.
