It's worth noting that you need two Retrievers for the combo to work, making it more difficult to assemble the combo.

Krark-Clan Ironworks is a card that could be a substitute for Heartless Summoning as its end result with Myr Retriever is the same. Maybe include KCI as Heartless 5-8?

I order from Star City Games, if I order internationally. I'm not sure, but I hear Channel Fireball isn't bad either.

As much as I like Golgari, my favourite Guild (flavour wise). Sadly, I've yet to find a Golgari deck I'm impressed with.

The Scorpion is both green and black, so yes, the Liege will give it +2/+2; +1/+1 for being green and +1/+1 for being black. However, the Liege doesn't boost the creatures in your graveyard (or anywhere other than on the battlefield), so it won't boost effect like Scavenge.

Mutilate would require a tweak to the lands, but you must remember that Sunken Hollow and Watery Grave count towards its ability.

For those wondering, you need minimum 5 mana to start off the combo.

With the Guildmage already out, you cast Lava Spike and splice Desperate Ritual onto it.
next, while Lava Spike is still on the stack, you need {2}{R} to copy it with the Guildmage. Casting the Desperate Ritual can help you get this, so it effectivly costs you {1}{R}.
Let the copy of the original spell (that's still on the stack) resolve, dealing 3 damage to the opponent and giving you {R}{R}{R}. Then before the original spell resolves, spend the {R}{R}{R} to copy it again. Repeat until the opponent is dead.

Lava Spike: {R}
Desperate Ritual (Splice): {1}{R}
Desperate Ritual (Cast): {1}{R}
{R} + {1}{R} + {1}{R} = {2}{R}{R}{R} = 5 mana

Them and Doubling Season are great cards, but often, one is strapped for space.

Axebane Guardian is another defender which adds mana equal to the number of defenders you control. It costs {1} more than Overgrown Battlement and has 1 less toughness, but it tapps for any colour mana, negating the need for Prismatic Omen.

Carven Caryatid is a 2/5 defender that draws you a card.

Traproot Kami is a better Wall of Vines.

Your artifacts are important, so Ancient Stirrings would be useful. It also helps lower the number of copies of non essential artifacts to about 2x, and important artifacts to 3x, lowering your card count.

Doubling Season would help speed up Darksteel Reactor and makes Eternity Vessel twice as powerful. If you can find a way to safely tap it, Gilder Bairn would help here too.

Vigor and Witchbane Orb don't seem to be doing much for you here. You need to drop 12 cards to reach 60, and these two, Sedge Scorpion and Dismantle look like good cards to drop, especially if you include some of what I suggest.

If you're playing the charge counter game, you may want to consider these:
Surge Node - Six charge counters on whatever you want over six turns. Twelve over six turns if you have a Doubling Season out.
Coretapper - A charge counter on whatever you want every turn, with a once off two charge counters by sacrificing it. Doubling Season works well here too.
Power Conduit - Moves around and / or changes charge and / or +1/+1 counters. Doubling Season will double the counters put onto the second target, ie. remove one, place two.
Shrine of Burning Rage - A possible replacement for Darksteel Reactor. With enough charge counter manipulation, Doubling Season, and / or Paradox Haze, the Shrine can reach critical mass quite quickly.
Golem Foundry - Another possible win condition. Works wonders with Doubling Season.
Everflowing Chalice - A good charge counter based mana ramp card.

Konda's Banner can only be attached to a legendary creature and you only have 3 legendary creatures in here. Might I suggest swapping it out for Obelisk of Urd? The Obelisk may have a higher cmc, but it also has convoke and gives the same average boost as the Banner.

I'd also take Coiling Oracle up to 4x, it is effectively a draw card for you (if it doesn't ramp you a land).

Sosuke's Summons might be worth considering for a steady supply of Snake tokens.

Force of Savagery, without some permanent effect pimping its toughness or an affect that lets it ETB with a +1/+1 counter, is put into the graveyard as a state based effect. This makes it so that you can't sacrifice it to any effect, including Ooze Garden's effect. The Garden is a good card though, especially with Groundbreaker and Force of SavageryJoin.

Lumithread Field and Leyline of Vitality are excellent Anthems for Force of Savagery, good call.
Gaea's Anthem and Glorious Anthem are the classic Anthems.
Spear of Heliod is effectivly Glorious Anthem, but with a nice creature removal effect on it. Too bad it's Legendary.
Hold the Gates and Always Watching can boost Force of Savagery's toughness and give it vigilance. Hold the Gates requires you to play Gates though.
Mighty Emergence will give Force of Savagery and Groundbreaker two +1/+1 counters when the ETB.
Adaptive Automaton calling Elemental will boost both Groundbreaker and Force of Savagery.
Hall of Triumph calling Green will boost both Groundbreaker and Force of Savagery, as well as your mana dorks.
Mimic Vat can make good use of Groundbreaker's and Force of Savagery's tendency to die easily.


These aren't exactly in colour, but they Fit the theme of the deck:

Master of Waves - Both Force of Savagry and Groundbreaker are both Elementals.
Incandescent Soulstoke - Both Force of Savagry and Groundbreaker are both Elementals. Incandescent Soulstoke can also cheat them in for {1}{R}, but at the cost of having to sacrifice them at the end of turn.
Elemental Appeal - {R}{R}{R}{R} for a 7/1 red Elemental creature token with trample and haste. You do have to exile the token at the end of the turn.
Zektar Shrine Expedition - Another source for a 7/1 red Elemental creature token with trample and haste.
Ball Lightning - I shouldn't need to tell you about this one, but it's the red Groundbreaker.
Flamekin Harbinger - A turn one tutor to fetch Force of Savagry and Groundbreaker. Also makes Nova Chaser a good choice.
Smokebraider - Tapps for two mana that can be spent on Elementals, which is what Force of Savagry and Groundbreaker are.

Surgical Extraction also helps with the Tentacruel problem.

Congrats Pushkin. Regardless of interests, you'll love the kid anyway.

Murphy can be a bitch, and in the worst of ways.

Depala, while a great card, is legendary, so I'd take her down to 3x.

Speedway Fanatic gives haste to any vehicle she crews.

Gearshift Ace gives first strike to the vehicle to a vehicle it crews.

Inventor's Apprentice is so good that I'd bump it to 4x (or at least 3x).

Renegade Freighter is a good vehicle. +1/+1 and trample when it attacks, plus any other bonuses from its crew (like Veteran Motorist's +1/+1) can make it quite formidable. It also only costs {3} to play and has a low Crew of 2. Second best vehicle imo (best being Smuggler's Copter).

You could possibly go down to 23 lands, clearing up space for more Aggro options.

Can't help much with Sideboarding without knowing the meta of your LGS.

A Wandering Fumarole or two mainboard can help both with mana fixing and as a beat stick. I'm playing a splash of white in my R control deck in Standard and my Needle Spires are proving to be awesome.

Word of warning, you may have to tweak the deck. It works fine in theory, but theory and practical are very different things.

Thinking of switching Lore Broker out for Languish / Mutilate. The mass sweep might be necessary mainboard.

The two sacrifice outlets I suggested have different roles. Viscera Seer allows you to scry into what you need, while Bloodthrone Vampire is a big beat stick.

"Free" draw spells are always good.

Evolving Wilds - Helps with mana fixing.

Brute Force - Better than Built to Smash. Gets you the same P/T boost without the limit of only targeting an attacking creature. Also, Built to Smash only grants trample to artifact creatures, which none of your creatures are.

Rush of Adrenaline / Brute Strength - better options than Built to Smash for granting trample.




I don't see the point of Pyretic Ritual. Kiln Fiend costs 2 mana. Nivix Cyclops and Wee Dragonauts require blue mana. I'd cut the Rituals for 2 more Temur Battle Rage and 2 more pump spells, like Furious Resistance.

You're very reliant on Ensoul Artifact. I'm not saying it's bad, but I'd personally add a few more cheap artifact creatures, like Signal Pest, and a few copies of Cranial Plating as a backup plan.

Wall of Resurgence is a 0/6 Defender that animates a land. Worth considering.

Scale of Chiss-Goria and Tooth of Chiss-Goria are noncreature artifacts with Affinity for Artifacts, making it easier to cast Metalwork Colossus.

Frogmite and Myr Enforcer also have Affinity for artifacts, giving you some earlier options for creatures.

Expedition Map helps you assemble the Urza lands.

Mourner's Shield isn't doing anything for you. You only have colourless cards, so the only damage it'll prevent is from colourless sources.
