I was trying to keep mono black when I originally designed it

I've done a similar combo in Modern:
Heartless Summoning + Falkenrath Noble + 2 Myr Retriever

I'm confused, why is Ashes of the Fallen?

I've been having lots of success with my GW builds after adding +- 3x Ready // Willing. The untapping and indestructibility of Ready have multiple uses in and out of any player's combat. I've even been able to cast the Willing side thanks to cards that add any colour mana (like your inclusion of Sylvan Caryatid) :P

Sadly, that I'm not too sure on. The more cheep (mana) creatures you have, the better it'd be. I'd say test with 2 and go from there to see what suits you.

As awesome as the Urborg is, it won't work in here. All my cards are only affected by the number of swamps I control, not the number in play :(

Still Tweaking this version of this deck. Not sure I have space for Quag Sicknessat 3 mana. Nightmare Incursion I don't have access to (I acquired most of this deck through trades) and even if I did, I'd run a different build for it.

Lands are permanents. Only Instants and Sorceries are not permanents

Lol, I'm not that old (28), yet

Sorry, my bad. Whenever I think of Elf decks, my mind immediately goes to token production. I blame this on years of playing an elf deck that produces, on average, 10-20 elf tokens on turn 4.

Fabricate, Slight of Hand, Serum Visions?

Some draw / search for the combo pieces (especially the scepter) would help a lot

It didn't exist when I designed this. Besides, the more I add, the more Rats I have to take out

One card I sue in my GR Liquimetal/Landshaper LD Deck is Ancient Stirrings.

Another Good card to target their artifacts with is Splinter

Provided you get your 'normal' upkeep, multiple Paradox Haze will grant multiple extra upkeeps. Seeing that you are relying on Jhoira, I suggest bumping her up to at least 3 copies and bump Paradox up to 4.

Having Both out at the same time mite require some form of reliable search and / or draw. If Coat is chosen over Door, Parallel will be a definite better choice. I prefer it because each is, in my opinion, more reliable in here that their counterparts.

Problem I've found with my elf token decks are the number of suggestions of high cost cards. Yes I should have the mana to play it (almost) every game, no I won't use it because it normally slows me down by a turn (because of the high mana cost). My meta is extremely fast or against the control decks, speed is all I have.

Coat of Arms mite be better than Door of Destinies for the more immediate pump.
Parallel Lives mite fit here better than Doubling Season as it costs 1 less mana.

More Puresteel Paladin is a good idea (for the draw), but another option is Quest for the Holy Relic

Sadly, Stoneforge Mystic is banned in Modern :|

This deck is Modern legal, Dark Ritual is not. Also the odds of you getting your removal and Wee being in every opening hand is impossible. Add to that the fact that what you're using is only one deck type.

That said, even if it's only 2 Nivix/Fiend, a backup can't hurt.
