Jund Regisaur Embercleave (Arena bo1) version 2 (Standard)

This is a second version of my other Jund Embercleave deck. The core of the deck is the same but the support cards are different.

Basically, I'm looking for a way to abuse Embercleave outside of Gruul. I've played a lot of Gruul this season and the deck is lackluster. You either curve out big and end the game early or you fizzle out and that is that. Not usually a lot of fighting back with the deck, outside of a surprise Embercleave.

The instant pairing that comes to mind is Rotting Regisaur + Embercleave. That is one nasty combo. If the opponent doesn't have removal for Regisaur, then turn 4 Embercleave is game. Even if swinging for 16 doesn't finish it, then the haste creatures will. This will be the decks starting point and I will work it further from their.

What I want from my 4/5cmc creatures is haste. I want to blow things out as fast as possible.
At 4cmc Questing Beast is the clear winner in the haste challenge.
At 5cmc the clear choice is Skarrgan Hellkite.

I want to add a second 3cmc creature and I have to look no further than the Gruul deck for this one. Gruul Spellbreaker is the perfect choice for an Embercleave deck. It has haste if you want to be aggressive or if you topdeck it, it can be a 4/4 to avoid 3 damage removal. Having hexproof on your turn makes it a great Embercleave target since it can't be spot removed when suited up and the trample is a big finisher.

Paradise Druid is the clear choice for a 2cmc creature. Ramping is exactly what the deck needs to be doing and playing three colors in an aggressive deck requires some extra mana fixing.

Turn 1 can easily just be playing a land tapped and saying go. I do however want a turn 1 play that is not hard on our mana. Enter Pelt Collector. We already want green for turn 2 and Paradise Druid helps it grow (and every creature after easily does so.) The opponent needs to remove Pelt Collector before it gets out of hand, but they also need the removal for every other creature up the curve.

Next I want to fill out my creature curve. My goal is x3 2cmc, x2 3cmc, and x2 4cmc. I want creatures that are easy to cast (so no double black or red):

a) 3cmc-
*Easiest choice, Bonecrusher Giant. 4 power, hurts to remove it, and removal on turn 2. Also, can be two sneaky damage to finish off a game late.

b) 4cmc- Thrash // Threat
I'm cheating and combining my creature slots with removal. Thrash is great removal with my giant creatures and Threat is a solid 4/4 body with trample. Nice bonus.
I'm bumping it up to three copies since it serves two purposes.

Mana Base
*My only consideration is if I should cut the x2 Fabled Passage for basic lands. I think the deck can afford them, they can be played tapped turn 1 with no Pelt Collector, turn 4 untapped, and sometimes turn three with a Paradise Druid helping to play a 3cmc threat. The games where it hurts will be far outnumbered by the games it finds that perfect land to hit everything on curve.

Here is where the changes in the deck start:
Cutting- 3x Rix Maadi, Reveler & x1 Collision // Colossus

Additions:
1) +1 Return of the Wildspeaker
doubles as major card draw and a huge anthem effect.
even if an opponent is playing around Embercleave, they will not be ready for this.
*forces Rix-Maadi out of the deck as we need cards that are non-human.

2) +3 Zhur-Taa Goblin
I had great difficulty finding a non-human worth playing here.
Stonecoil Serpent was my favorite choice, however it cannot be targeted by Thrash and that is a big liability.
I looked at Rimrock Knight, however it is too easily blocked by every small creature in the format.
I considered upping the amount of Bonecrusher Giant. The plan was to just cast Stomp on turn two of every game I don't have Paradise Druid. Kill any potential blocker first and the face as option number two. The problem is that Pelt Collector stays a 1/1 in that scenario.
*The goblin is a harder cast turn two but 3/3 or haste is valuable at multiple points of the game.

Notes:
This version of the deck is basically the current Gruul splashing black for Rotting Regisaur. I want to avoid the current Gruul build, however Regisaur may be enough on its own to change the feel of the deck.
