Are you actually trying to make a modern viable deck? Because if so, there are likely some changes you should make. Admittedly this is a slightly more expensive proposition.
The core combo to make elves strong in format like modern and legacy is Heritage Druid and Nettle Sentinel; you tap elves for mana using the druid and then the sentinels untap when you play the elves, letting you get more mana for elves. Potentially you can put your whole hand in play on turn 2.
For cards to remove, Rhonas's Monument and all 4 and 5 cmc spells in your list aren't strong enough for modern. Your land count is also rather high.

Thank you for your input, I don't actually plan on entering in competitions or anything, but I wanted to know what people thought of this as a modern deck. If I had the money I would definitely have the more expensive cards. I've always considered nettle sentinels and heritage druid, so I'll try that out.wisegreenbean

As a general critique for a modern deck, it's biggest issue is low win-con density. You'll have a very hard time winning without drawing Ezuri or Joraga, or god forbid, ulting Nissa. Immaculate Magistrate could piggy back you a win, but it's sooooo slow. The rest of the time you're just mucking around with a bunch of mana and a bunch of 1/1s and 2/2s. A lot of times you can get 6 mana on turn 3 and then have little to do with it; mana sinks are important. Craterhoof Behemoth is classic and correspondingly expensive; a bit more affordable and still fairly playable is Regal Force, to refuel.

What do you think of Sylvan Messenger as a cheap way to replace collected company or chord of calling? wisegreenbean

It's not amazing, but I would regard as a pretty strict improvement to your deck at the moment, over your Nissa Revane and Nissa's Chosen, Immaculate Magistrate, Rhonas's Monument, 3-5 forests, and Primal Command, in that order from bad to less bad. Jagged-Scar Archers is also dubious. All of those are pretty clear stinkers that you could cut for a lot of things that would improve the deck, including Sylvan Messenger. You have 17-22 pretty easy cuts to make, which puts you in a position such to be creative.
For 4 mana, Sylvan Messenger doesn't have too dramatic an immediate impact, and can whiff pretty hard. Sometimes you'll spend 4 mana for a 2/2 elf, with no added benefit apart from getting 4 nonelfs off the top of your library. That hurts, and will happen ~6% of the time; when that happens, you probably lose the game. The typical outcome of getting 2 elves is not too bad, though, making it roughly playable.
