Going Cosmic with Five Color Spiders in Commander

Posted on September 23, 2025

Hello and happiest of days for each of you happy folks! Today I wanted to give Cosmic Spider-Man a spin leading my next Commander brew for you all! Let's look at this fun little Five Color leader!

This five-drop on curve 5/5 Spider Human Hero has a massive five evergreen keywords in flying, first strike, haste, lifelink and trample like a better Akroma with no protections but lifelink instead. Then when your combat is about to get it on your other Spiders also gain the quadfecta. Not bad right? I am going to try this guy leading a kindred brew around tossing them out.

Ramp, Lands, and Stuff

Now let's start with Kindred and general ramp. This five-drop mono-Green 4/3 Spider Hero will ETB and then ramp a basic tapped. And he's got web-slinging for three too. Then the Manalith costs three, taps for any color, and acts as an Anthem for your Spiders too. Love it here all up and down the block.

Now let's turn to Mana Dorks. Spider Manifestation has reach to shut down attackers and then taps for either Red or Green. Then you can get a free untap when you cast a four-cost or more spell! Then the Artifact Spider Toy Twitching Doll taps for one mana of any color and then tosses a fun counter here and then you can tap and sac this for no mana but at sorcery speed to make 2/2 Reach Spiders equal to the counter count here. Then the three-drop Human common Guy in the Chair taps for any color, and then at sorcery speed to toss a+1/+1 counter on your Spider for three mana. It's great here.

This Selesnya duo are not Spiders, but key mana dorks. The Elf has a 4/5 vigilance body with 4/5 on a four-drop and then as we cast creature spells, we can make Merc tokens and then after swinging tap her for mana equal to our different powers. Then the three-drop vigilance Treefolk will tap for mana equal to our color count, and it's also got that count in size too.

This two-drop colorless artifact dork Spider-Bot will ETB and then toss a basic onto your library's top. Not bad for an on-curve dork. Then the White tapping legendary land Minas Tirith will often ETB untapped, and then tap with two to draw if you attacked with two this turn - easily done here.

Now let's turn to this kindred caring land section with the next four cards. The common version of Command Tower ETBs tapped but if you cast something with your Commander's creature type, you can scry one. Then the land above chooses a creature type and then taps for colorless or one of anything for that chosen type and then it cannot be countered too.

The legendary land Three Tree City chooses Spider on arrival, taps for colorless and then with two for each Spider you control! Then the last land Swarmyard also taps for colorless and then for free to regenerate Spiders. I also included all ten Tri Lands and Surveil Duals.

Lords and Token Makers

Next up fun Lords and Spider makers and carers! This four-drop enchantment in Green arrives with a 2/1 reaching Spider and then you gain life equal to your Spider count! Then they all gain +1/+1 in size and then cannot be blocked with defenders. Then the Bear cost and size will ETB with a Food token and then will be a Lord for your Spiders and other animals too.

Spider Spawning is next with flashback for another two mana. You will make a 1/2 Spider with reach for each dork in our graveyard - that's another reason the surveil lands are here. Then that 0/2 White uncommon Human Aunt May will gain a life for each dork that arrives and then pump with a counter if a Spider. Great Soul Warden variant for this deck to also pump the team.

Now this Spider rare Green duo with reach will turn opposing casts of opponent's stuff into token and Spiders. The former Gruul six-drop 5/6 will do it for anything our foes cast but 1/1 side and Insect. Then the legendary latter four-drop 3/5 enchantment dork will make a 1/2 Spider with reach but then just for instants or sorceries.

Synergies and Win-Cons

Alright happy folks! Now let's turn to synergies and backup win-cons too. The five-drop mono-Black planeswalker with four loyalty gains it as our stuff dies, and then that's tokens too! Then you can +1 her to draw and lose a life or -3 her to make a pair of Spiders to protect her or swing at 2/1 with menace and reach. Then her ultimate at -8 is feasible with that static ability - don't sleep on it as a fast win con. Then the six-drop lady on a 4/4 size is a Future Sight on legs for Spiders or non-dorks. And when you swing, you can mill to get another one or get more fuel for graveyard stuff. Then the three-drop 2/3 changeling will arrive and do the same for Spiders too.

Now let's turn to back-up win cons. The three-cost Red enchantment Shared Animosity will let our team turn swings by our stuff into power pumps equal to the other attackers with that creature type, so Spiders with the haste of Cosmic or that have been around can kill fast. Then that five-drop Spider Ghost-Spider, Gwen Stacy has an attack trigger to shoot the defender equal to our attacking squad! Then Ishkanah, Grafwidow ETBs with three more 1/2 reaching Spiders if you've got delirium with surveil, and then the previous thing above. Then mana sink seven here at any time to shoot a foe for damage equal to our Spider count!

And now back to synergies. Shelob, Child of Ungoliant is a nice-sized 8/8 with deathtouch and ward 2 also gives that combo our Spiders! Then when they would kill you can make a Food token copy of them! Then the two-drop Rioting Spider-Punk in Spider form also gives riot to our other Spiders which is a great way to ensure they attack now and then all spell and abilities cannot be countered - that's your stuff and your foes' too. Then damage also cannot be prevented.

And now...this duo! The flying Bear in Azorius colors is a rare Spider Hero turns opposing creatures and artifacts into arriving tapped - brilliant in tempo for this on-curve lady. Then the uncommon Green two-drop 2/3 legendary Spider Hero with six mana web-slinging and if you pay it arrive with two 2/1 Spiders with reach and then gain some life too.

The three-drop mono-Green Spider Spirit Spinner of Souls is a 4/3 size and then another nontoken dork dying death trigger to dig and draw the top one! Note no breaks there like once/turn beyond it has to be a nontoken. Then the Dimir four-drop on curve 3/3 Spider Hero Superior Spider-Man arrives as a Clone of any creature card in any graveyard! And it stays that size and types and name.

Now let's finish with this trio of Green Spiders! The first rare 1/1 one-drop with reach and deathtouch can be sacked for two at sorcery speed as a Tutor for a Spider Hero! Then the four-drop 2/4 Golgari reacher can exile a dork from our graveyard to make a 1/2 Spider with reach and then each foe each damage equal to our Spider count - that's our recursion there. Then the six-drop Spider Hero with a 5/5 vigilance and trample - good combo there is last. Then when he ETBS or gets his swing on all other dorks are pumped in size and trampled too like a mini-Overrun.

Answers

And now...answers! The five-cost sorcery in Blue will bounce all non-Spiders to hands - yours too. Then I added the three-mana Common kindred changeling so Spider to exile and leave behind a 1/1 and then I also tossed in Nameless Inversion for it as a changeling removal spell. Then the two-cost flashing 3/2 will be given flying at one mana or sac with one to give our stuff indestructible for the turn to save them, I also tossed in Heroic Intervention for that.

Now let's turn to Spiders with ETB kill abilities! The four-drop Golgari 3/3 reach Skyfisher Spider will sac another dork, and it can be a token. Then you'll get a free non-land Vindicate! When this dies you can self-exile to gain life equal our creatures in graveyard count. Then the five-drop 2/5 reacher Stingerfling Spider will ETB for a Wing Snare. I also tossed in Gloomwidow's Feast to destroy one at instant speed and leave behind a token!

And now two mass removal spells. My favorite ever Spider is the five-drop 2/7 Silklash Spider that has enough toughness to block forever, and then as they fill their board with flyers, sweep them for X activated or add to damage they ate to kill them off. Then the seven-cost Black sorcery Kindred Dominance will kill all non-Spiders on resolution!

Card Draw

And now...card draw! The five-drop rock will pump our Spiders and then when we cast them draw with no limits! Then the two-drop Selesnya Bear will draw when they ETB, and tokens too, but just once per turn. The five-mana enchantment will draw when they ETB or attack too.

Distant Melody will draw once for each of our Spiders. Then the four-drop White Spider Hero Spider-UK will in our endstep draw and gain you 2 life too if two or more dorks arrived this turn! That's also tokens and web-slinging which he has. Then the 1/8 Spider Doom Weaver with soulbond will draw when it dies equal to its power.

Now let's finish with this two Dimir combat damage trigger Spider Heros! The three-drop Dimir 2/4 one will turn combat damage into digging the damage dealt and drawing one and you can exile it from our graveyard to make your dork gain this abilities and grow in size too.

There we go! Want to see my brew?
