Agreed. That calls into question the use of Urborg though, as you're now just splashing black and don't need it for any combo pieces. Something like horizon canopy makes more sense to me as is, but that's just me.

Interesting build. Treekfolk Harbinger would seem right at home here, but that would further tip the balance into green which might be problematic.

What format and budget are you going for here?

I absolutely love this idea and this build, let me ponder (I wish) for a bit about updates.

On the assumption that this is a casual/budget build and/or budget/legacy, here's how I would build the deck from the bones of what you've got going here.

The major tweaks are removing most of the blockers and upping the control factor.

What's the budget and format you're going for here?

That's probably true, I've gone back and forth on the spellbomb-esk cards for a while

I think I'm getting the gist of this one, but I need a little more info. Are you going for competitive? What's the budget?

My advice here is take the lands down to 22, take out Rise of the Ants, and add in 3 x Fecundity. Your curve is mighty small with all those 1-drops, and you don't really have enough advantage from the 'need land' cards to justify half the deck being dead drops once you hit your operational curve of 4.

What's your budget, format, and level of competition here?

Salvage was definitely a consideration, but I opted out due to the three colors. Conflagrate sounds mighty good though

I don't like zombie infestation in here. It lets you dump rats from your hand but it nukes your hand in the process for very little benefit (3 cards for a 2/2). A more efficient way to get what you need in the grave is through dredge mechanics. Golgari Thug puts stuff in the grave and lets you pull back Eternal Witness in the process. Golgari Grave-Troll is the king of dredge.

First thing that leapt out to me is Underworld Breach. It's 6 bucks, which might not fit the budget, but is an in-game cheaper version of past in flames.

Are we going for budget modern here? Casual?

Ten 4-drops and twelve 3-drops seems a bit high, even with 24 lands. You're going to be much slower on average than the fast decks tearing through modern at the moment, such as hammer time, jund, and izzet tempo, and everything that takes advantage of lurrus. You're also now legally allowed to use counterspell in modern, which is a must-include. Then there are the tech lands to consider.

Just my thoughts, not a condemnation.

Ah, true. I forgot to look there. I know next to nothing about Pioneer.

Since you've got a super high volume of 2-drops, you could run some of the great land/non-land combo cards from Zendikar Rising such as Kabira Takedown or Sejiri Shelter (since you don't need an untapped land turn 1). You could also run Mutavault which just helps everything in here.

What format, level of competition, and budget are we going for here?

I always try to work in mutavault when playing around with gravecrawler. Might not fit in here due to your high need for double black, but worth mentioning.

I'm pretty out of the loop these days, so I never really checked out Regent, or many of the other cards you mentioned. I even missed out on consider, which is a delightful card.
