Mortlocke on New hubs to be added

3 months ago

Hello legendofa,

I propose a new hub to be added: Phyrexian. During Modern Horizons 2, 225 creatures were retconned into having the Phyrexian creature subtype to join Vorinclex, Monstrous Raider . Additionally, there were a smattering of Enchantments, Artifacts and etc that ether have the Phyrexian subtype or create creature tokens that do. Thanks to this retcon I now have a deck that has a Phyrexian tribal theme. For your reference, below is a full list of spells that were affected by WotC's Phyrexian errata.

Very nice deck!

Septic Rats doesn't seem to work well here - it is the only card that deals damage in form of poison counters, so if you won't manage to deal 10 damage with 2 of them in the deck, they won't actually do anything. Unless you want them just for block using -1 counters... Maybe Swarm of Rats ? I know they are much worse than Pack Rat, but you already have 4 of these. The majority of your creature spells cost 2 mana (18/30) I would consider using Aether Vial and stop on 2 counters to speed up the drops I don't really get the Fabled Passage here. How is it better than just swamp, since the only card you can take with that is swamp and it may come tapped? I would rather use Swarmyard s instead

Most of my experience with infect comes from playing simic, but I have played the mechanic in all 5 colors. In terms of power, green is the most effective color to play by a very VERY large margin. You get access to the best infect creature in Glistener Elf (along with the slower and safer option of Blight Mamba), you get trample sources to push through damage with Ichorclaw Myr such as Rancor, Predator's Strike, and Larger Than Life, you get protection bundled with buffs in the form of Vines of Vastwood, Ranger's Guile, and Blossoming Defense, and you get the largest pool of very strong power boosts in the form of Mutagenic Growth, Invigorate, Scale Up, Might of Old Krosa, Berserk, Become Immense, Groundswell, Phytoburst, Noble Hierarch, and Pendelhaven. Since infect is an all-or-nothing sort of archetype, even when running the less aggressive versions, the most important characteristics that you need are speed, protection, and evasion. Green offers two of those things in spades but can struggle with evasion. This is why blue is generally considered the next best color to run. You get the insane threat of Blighted Agent, unblockable buffs with Distortion Strike and Aqueous Form, and protection from spells via Spell Pierce, Dispel, Turn Aside, and the odd Spellskite. Black is the next best. Plague Stinger's flying isn't as good as the unblockable on a Blighted Agent but it's still very powerful evasion as illustrated by the ubiquity of Inkmoth Nexus in every non-budget infect list ever made. Black also nets useful control tools like Thoughtseize, Inquisition of Kozilek, Fatal Push, Dismember, and Assassin's Trophy. White was considered the worst infect color for a very long time since its best option (Apostle's Blessing) can be used in any deck, but the recent introduction of Giver of Runes has breathed some life back into the color. Additionally, I've seen a lot of equipment lists popping up that use Colossus Hammer, Kor Duelist, Sigarda's Aid, and Kor Outfitter to see some success. Unfortunately, that leaves red as the current worst color to run in infect. It has some decent buffs but they pale in comparison to green's offerings. The result is that most red infect decks rely on gimmicks like using Razor Swine's first strike to wither enemy creatures, generating infinite mana to pump into an unblocked Ogre Menial, or putting Phyresis on something like a Spikeshot Elder to bypass combat altogether. Your instant tricks definitely fall in this category. That's not necessarily a bad thing though. If your meta is casual enough, red should still work and it will be much more interesting to play with / fun to play against than a more traditional deck. How competitive you want to be is always up to you.

To answer your specific questions, I would probably start by cutting a few creatures. Most lists run about 12 infect sources (and that's including a playset of Inkmoth Nexus). With Hand of the Praetors on your top end, running 16-20 isn't that unreasonable, at least as long as all of them are good. Infect creatures usually become "bad" when they cost more than 2. That's why I wouldn't usually recommend running Ichor Rats or Septic Rats. Both Necropede and Plague Myr are perfectly acceptable inclusions with very similar power levels. They'll rarely be better than Plague Stinger or Ichorclaw Myr but that's okay if you just want more guys to play. As for Vector Asp, it's honestly a pretty bad choice in most circumstances. While you usually won't need to activate it more than 2 or 3 times to win the game, that mana would be better spent elsewhere, and it doesn't even trigger the Hand. However, given the choice of it and a 3-drop, I'd probably take the snake, especially since it would be your only proactive play on turn 1 (barring the inclusion of Glistener Elf or Inkmoths). Better though would just be to run neither and invest in more buff spells to assist in combat and trigger Livewire Lash. I do like the idea of those spells having cycling in theory, but in practice, the mana needed to cycle can short you of the resources needed to close out the game. Plus, cycling spells tend to cost more to account for the added ability. Cycling lands on the other hand should be fine as long as they come in untapped, although it looks like that only describes Ash Barrens and Blasted Landscape. Just like with creatures, I wouldn't run any spells that cost more than 2 unless they can win you the game like Soul's Fire can. This will also allow you to run 20 lands or fewer, opening up even more slots for gas. I apologize if I'm repeating myself about the low-cost-high-speed thing but that is basically the reason the infect mechanic exists. If you prefer a slow and more controlling style, Rakdos wither built around Necroskitter is a fun option that has some overlap with infect.

Septic Rats and Ichor Rats are both good creatures here.

I would suggest these revisions to the mainboard: +4 Phyrexian Crusader -4 Scar


-2 Swamp +2 Memorial to Folly


-4 Swamp +4 Inkmoth Nexus (I know this is a budget deck, but I believe this will receive a reprint soon, and while 1-2 copies is expensive, it won't break the wallet)


-2 Septic Rats +2 Ichorclaw Myr


-2 Blowfly Infestation +2 Nest of Scarabs


+1 Skithiryx, the Blight Dragon -1 Virulent Wound

CardTyrant! I love this deck and decided to build it myself with a few alterations after playing it with my group. Have you considered Altar of the Brood for an instant speed table library mill? With all your single creature pump spells, an infect creature like Septic Rats could also be a welcome addition instead of something less impactful like Typhoid Rats or Rancid Rats. You can even just have it ping people to fatal infect damage using Thornbite Staff after it gets big enough! That especially helps after the anthem effects(i.e. Caged Sun, Door of Destinies, Eldrazi Monument, etc.) makes it so Marrow-Gnawer + Thornbite Staff no longer kills your rats to enable the infinite combo. I also really enjoy Torment of Hailfire with all the mana we're generating. There are a couple more things i've changed in mine, so please let me know what you think! Here's mine.

Sorry about the rather late reply, but here it goes!

@lukas96 I just want to point out that the Midnight Banshee + Kulrath Knight lock out combo is one of the win cons in this deck; assuming you're facing non-black decks. Also this deck is meant to be a foundation to build off of, you make the changes you believe are required for your playgroup; even if that means messing with the mana base!

@DemonicExecuter This question is always hard, and tends to be heavily affected by your playgroup. If your playgroup doesn't abuse flying creatures, you could probably get away with replacing 2-4x Plague Stinger for 2-4x Ichorclaw Myr; otherwise I wouldn't bother with Ichorclaw Myr. On the other side, replacing the 4x Septic Rats for 4x Phyrexian Crusader should be a safe bet in all situations (same CMC, same stats, better effects). Finding the proper card to replace with Skithiryx, the Blight Dragon is kind of tricky, but I'd say 1x Kulrath Knight. I honestly would say as awesome as it sounds, a 2BB Black Sun's Zenith would eliminate 14 out of the 22 creatures in this deck (if un-buffed by Hand of the Praetors); not to say it couldn't work, but you'd have to build with it in mind.

@ShadowFire1 this question really boils down to Contagion Engine vs Contagion Clasp - I'd say the clasp wins out simply because it's faster and doesn't have the potential of clogging your hand as much in the early stages; its a 2 mana Scar that will later be used to proliferate. The 4 extra mana on the engine changes the targeted -1/-1 to apply to all of a target player's creatures, which just feels more clunky than helpful imo.
