Have you considered Murder Investigation? It fits the theme really well and turns anything into a Hangarback (minus the flying on the tokens).

Also, 1 Swamp with some way to fetch it (probably just Evolving Wilds) is a neat way to fuel Bone Splinters if you want to force the issue on spawning tokens from one of your creatures as a way to just overrun the field.

Murder Investigation when compared to Hangarback Walker is very inefficient. You are spending whatever the CMC of the creature and then another 2 mana on Murder Investigation to get an outcome that is not as good as if you had just played a Hangarback.

Also, adding a swamp for a card like Bone Splinters doesn't make sense. Would that make this deck so much better? I don't think so. In order to warrant splashing for a specific card, that card has to make your deck a lot better, which, IMO, Bone Splinters does not. I think you would, most of the time, end up with a dead card in your hand and a sorcery speed one at that.

Murder Investigation isn't a replacement for the walker it's an "also" - turn your Managorger into a pseudo hangarback for example. It's a lot more mileage a few turns in than you would get out of a late play Servant for example.

You're right on Bone Splinters not being the best force-sac (to spawn tokens on demand, say if your hangarback was going to be exiled or otherwise disabled instead of killed).

Celestial Flare (staying white but limits to combat phases) or Altar's Reap (splashing black) are instant speed choices.

It's a utility option that may not really pan out in practice but may be worth a look. YMMV, I'm just working on theory

Thanks Trynthlas, I've been thinking about Murder Investigation since you suggested it, I've come up with something that seems to work. 4xBlisterpod, 4xMurder Investigation, and the 4xHangarback Walker's give a LOT of tokens. I've been testing it and it seems to work best with a very low mana curve, the only 3 drop can be Managorger Hydra so you can fetch a lot of creatures with Evolutionary Leap and play 2-3 of them in a turn.

Blisterpod is awesome in this deck, except it doesn't combo with counters. This is such a great turn 1, opponents will so often not attack or block it for an extra turn or two because they think you want it for mana ramp. This one-drop can buy 3-4 turns itself. Later you sac it to draw two creatures.

Here's what I'm thinking now, You can't fire me because I quit - G/W Count copy

The sideboard is weird, you can play this original mainboard with the sideboard. Or the Murder Investigation deck could be this decks sideboard. Either way, the idea is that you can switch between lots of tokens and big flying creatures while leaving enough spots for some good removal.

Let me know how it does if you play it! I like the ability to really switch up the deck's threat matrix with the sideboard configuration you have. I do wonder if Blisterpod has the same "won't attack" effect after the first game? (you tell me!)

A few other 'food for thought' cards... (which you may have already considered)Retreat to Kazandu for additional counters that goes really well with Hardened Scales, especially with fetch lands (it's a reason to put even more of them in the deck, too!). Play fetch land, 1 counter + 1 for each Scales, crack it and play another land, doubled the counter. Option 2 on the enchant is also good for some life in a pinch.

Picture the magical Christmas land early-game scenario: Turn 1 or 2 get a Scales out; Turn 3 Managorger; Turn 4 play Retreat (+2 counters on Hydra), play fetch land (+2 counters on Hydra), crack fetch land (+2 counters on Hydra), play another 1 mana spell (+2 counters on Hydra)... 7/7 or 9/9 trample critter on Turn 4. Or split the landfall counters up if you did a T1 or T2 creature drop.

Inspiring Call for indestructible at a key moment, and/or hand-refill, which comes in handy when you have all cheap stuff and can empty out your hand pretty easily. Great sideboard card with a counters deck IMO.

Scale Blessing which just gets retarded between Managorgers and Hardened Scales. Only really good if you're able to keep 3+ creatures on the board though (that's my super-scientific analysis) due to the mana cost and more of an anthem effect.

I don't think the Murder Investigation deck could support even one more non-creature spell.

Inspiring Call could replace Evolutionary Leap if you wanted to take the deck in a different direction, I don't think they make sense together.

I'm exaggerating the strength of Blisterpod a bit, but even if you just chump block with it twice, it should buy enough time to stabilize the game. I've played many games where I fall behind and can only keep one creature on the table, I've run myself out of creatures in my library twice now, if I had blister pods, or Murder Investigation, I think I could have gained an advantage and made a come back.

I only play with friends who know every card in my deck and FNM at my local card shop with a small group of regulars, there isn't much chance of really surprising anyone, often by the second match everyone knows generally what everyone else is up to. The switch sideboard could still work though, the opponent will still likely make bad decisions by guessing what I'll side in. I should get to test out the new list next week.

have you thought of Gleam of Authority and Feat of Resistance

musiclover, ya I ran 4xGleam of Authority along with Den Protector. That was great, but going with Evolutionary Leap now it doesn't work as well. Basically I'm sacrificing creatures to protect them rather then relying on cards like Feat of Resistance to actually protect them and so Aura's are likely to just get lost 2 for 1.

Murder Investigation is different, because you want that creature to die.

PlagueRats how much trouble have you had with Enchantment hate, or creature exile via enchants (Silkwrap, etc)

Enchantment hate hasn't been much trouble, people usually only have 2-4 cards enchantment removal cards in their side board, I have 4 of each, plus 4 Silkwrap that I'd likely side in against Dromoka's Command to outnumber it 12-4.

My buddy plays about 12 exile removal spells in one new deck and it doesn't hurt that much. He's pressured to kill my death benefit creatures right away, so usually he's spending his best removal on my 1-drop Servant of the Scale or a 2-drop Hangarback Walker. Once I play Evolutionary Leap I can usually come back from anything and beat him.

With the new Murder Investigation version, the idea is I'll just outnumber any opponent's exile spells by a lot plus still have 4 Evolutionary Leap's.

Ah, someone else who believes in Evolutionary Leap. Stubborn Scales is my list. I've only been running 2 because the first one is sufficient, and Stubborn Denial serves as additional defense against removal.

Yes. You should only run 2 Evolutionary Leaps. Having multiple copies in hand/on the board does you no good.

Evolutionary Leap won't work in every deck, but my deck and play style are all about it, I would run 5 of them! If the game goes long enough Evolutionary Leap draws every creature in the library. It's endless creature fetching that scales perfectly with every games board state. 'Protecting' Hangarback Walker's is just a free upside. This deck is usually more about stalling the game then winning fast.

Sorry if this was already a suggestion, but have you considered Undergrowth Champion? Obviously you'd need to use more fetchlands but it might be worth a test. He's a resilient combatant at the very least.

JakeHarlow, I figured Undergrowth Champion wasn't good enough for the top of the decks curve. Last time I really considered it they were selling for $25 though... In some situations it would be much better then an Endless One. I'm going to think about it for a while, thanks
