Arachnogenesis Discussion

NV_1980 on Stumped by twigs on a stick

I like Shape the Sands, but I'd rather use the instants that boost all my creatures instead of just the one (eventhough these instants do have a higher CMC). Arachnogenesis is very nice, but I don't feel like I need it in this deck; it already has plenty of defensive capabilities.

Your deck looks well-oiled, it probably functions great, but I'm not going to upvote it for two reasons (please don't take this personally):

  1. I never upvote decks that focus at least partly on the infect mechanic. I know this mechanic is part of the official rules and everything, but I feel it's broken; especially in EDH. Our playgroup has banned it because of that (even after we'd tried for a while to up the limit of poison counters to 20 instead of 10 in EDH games).
  2. Felidar Sovereign (and similar cards, which luckily aren't in your deck); imho the most cheesy way ever to win a game of EDH. I have 40/50+ life, so that's why I win. It just feels wrong to me to use this card in EDH, almost like cheating. And it just takes all the fun out of it, if you ask me.

Arachnogenesis and Shape the Sands are quite cool also.

Please look at my deck and upvote it if you like it.

Cool deck, upvoted!

What about Kin-Tree Invocation, Wave of Reckoning and Arachnogenesis?

Check out my Doran EDH, there are many more similar cards in there:

You seem to be going tokens pretty hard here. Primal Vigor is another card that provides a doubling effect. And no spider tribal list could be complete without Arachnogenesis.

Awesome! I'm so glad to see Arachnogenesis in this deck. I love that card! Especially in multi player, it can get crazy lol

Hi Guint!! Here are some suggestions I think you could utilize for Ishkanah. So far it looks good!

The things we want to make sure you have in this deck are ways to activate delirium, as well as ways to activate Ish's tribal effects. Let's start with the spiders themselves~

Now onto the Delirium Mechanic. Making sure your own cards into the graveyard can seem counterproductive but a lot of things benefit from it. So first, how do we self mill?

Now for some super fun cards that benefit from a graveyard presence.

Now lets talk about Black and Green as colors in EDH. Black/Green has a few things that it needs to run undoubtedly. One of its major problems is card draw, so you're definitely going to want to auto-include Harmonize and Phyrexian Arena. I would also consider Lifecrafter's Bestiary.

Removal: Putrefy, Murder, Hero's Downfall, Abrupt Decay, Krosan Grip, Golgari Charm, Toxic Deluge, In Garruk's Wake, Acidic Slime, Beast Within. Dictate of Erebos to be used in conjunction with a sacrifice outlet like Ashnod's Altar (sac your extra tokens for mana!)

Protection: Asceticism, Swiftfoot Boots, Lightning Greaves, Heroic Intervention

Tutors: Green Sun's Zenith, Diabolic Tutor, Demonic Tutor

Ramp: Cultivate, Kodama's Reach, Solemn Simulacrum, Sol Ring, Explosive Vegetation, Thran Dynamo, Commander's Sphere, Golgari Signet, Cryptolith Rite, Harrow, Crop Rotation, Sakura-Tribe Elder, Yavimaya Elder.

The only other thing I want to say about your deck is that you should probably up your land count to at least 36. 30 is usually too little for most EDH decks in my experience. Unless you're going super aggro, you'll find yourself short on a lot of land drops.

If you wanted to upgrade your lands, here are some relatively inexpensive things you could add:

Golgari Rot Farm, Command Tower, Jungle Hollow, Temple of Malady, Woodland Cemetery, Overgrown Tomb, Llanowar Wastes, Tainted Wood, Grim Backwoods, Bojuka Bog, Hissing Quagmire, Temple of the False God, Drownyard Temple, Ghost Quarter, and any lands that Cycle in your colors :)

It might help you to get some haste enablers for your commander so you can eat up 5 tokens and slam into your opponents face without giving them a full round of turns to deal with your 25/25.

Swiftfoot Boots

Lightning Greaves


Brawn sac him and it will give your guy trample

Flamekin Village

Ogre Battledriver

Xenagos, God of Revels

First off I Your breaking your rule a bit by using Silklash Spider. It has a face on its butt, its fighting a dragon, and it is a spider of behemoth size, but it is also one of the best spiders ever printed so whatever.

Here are a few suggestions for this deck Arachnogenesis, Spider Spawning, Penumbra Spider, and Swarmyard.
