I'm unsure how to feel about that. Dark Depths is good, but, trading fetch lands.
I like to play with everything, so needing fetches of every combination is a thing for me.

Oh I know, I've played with Infect and against it. I've played against most Tier one legacy decks, they're fun for sure. Currently I'm running the Painter-Stone combo. Elves or Affinity are my go-to decks though.

To be fair, a turn two Dark Depths is basically the god hand and/or top deck. Dredge is just a strong deck, to be competitive against dredge he could easily sideboard Tormod's Crypt or Grafdigger's Cage. Re-animator is also answered with Crypt/Cage. You're also talking about money decks, and to be completely fair, money decks will always be hard to beat on a budget. I mean, a turn one Griselbrand is still hard to deal with even if your playing a legacy competitive deck.
I mean, this deck will crush, I mean crush Sneak and Show if they don't have a force of will in hand.

Not so much, Tutor is turn 1. Souleater is turn 2. So if you have it in your hand, cool, but tutor is an enabler that greatly increases the odds you're going to drop it on turn two. If they're going to force of will your tutor, then they'll force of will your Souleater if you don't play tutor.
In modern you'll see your fair share of counterspells and removal. Counters and removal is in every format. Making it modern legal honestly won't make winning with this deck any easier.

Why? Against any competitive modern or legacy deck if you haven't won on turn 3 with this deck odds are good that you're going to lose.

Question still stands on what to drop for a 4 mana creature.

Over what though? On turn 4 the game should be over. If it isn't then turn 4 should be spent drawing cards, or dropping the card he needs to win, like a dragon or souleater.
Faithmender is a decent card, but does it have a place here?

Have you thought about Blood Artist over Souls of the Faultless? Looks like a fun deck.

You're welcome. :)

Well, time to make a high tide deck.

Actually it does, variable X in bond of agony is the amount of life you pay to cast it. So it costs 1 mana and X life.

I guess it depends on what your thoughts on "budget" are.
You should add 4 green sun zenith's, because the ability to find anything you want in your deck is nice.
I would do this;
-3 Wirewood Elf
-1 Wellwisher
-2 Hand of Emrakul
-3 Geistcatcher's Rig
-1 Leaf Gilder
-2 Fog
-1 Gilt Leaf Ambush
-4 Llanowar Elite
-2 Krosan Driver
-1 Taunting Elf
-1 Tranquil Thicket

+4 Priest of Titania
+4 Green Sun's Zenith
+1 Elvish Archdruid
+ 2 Elvish Mystic
+2 Timberwatch Elf
+4 Rancor
+4 Drove of Elves
+1 Wirewood Lodge

And having the Eldrazi is nice, but maybe Ezuri, Renegade Leader over Scavenging Ooze and Ulamog's Crusher? I will be the first to admit that I'm not the most knowledgable on budget cards, but the core of a good elf deck is usually within budget. As stated above, depends on what your definition of budget is.

Browbeat over mad prophet? Swords to Plowshares over one of the pro color spells?

If you want to be a truly rude and terrible person, splash black for tainted strike.

Since the meta is now all monoblack, meh. I mean, it was a good deck and I top eighted both fnms, but the meta game runs about 12 kill spells and 8 hand hate cards. I will tell you that a monstrosity fleecemane lion with unflinching courage is the most adorable thing I've ever done.

This is what I ran for a couple weeks. It was fun, but I have since changed it to live the dream with tokens and purphoros.

Well thank you good sir/ma'am.

Have you thought about just dropping red entirely? Plummet, Selesnya Charm and mainboard two deicides and the full playset of banishing light?

Yerp. Whenever I play anything legendary, or any planeswalker I usually only run 2 or 3 of, since you want to draw it, but drawing them when they're still on the field is just a dead draw. It really depends how necessary they are to the deck function.

Lies, the glass is always full.
