I think you should add more equipment card to this deck. I can't suggest any since I'm awful with equipments, but more should be in the deck. I don't think 3 will cut it.

Day of Destiny is a legendary enchantment though. Glorious Anthem isn't. I was suggesting it so that you could have multiple copies of them out at a time so you're creatures would get a bit more of a boost.
Just realized, why do you not have Mirror's Gallery in this deck? Wouldn't that help it move even faster?

Glad I could help.

If you have out things that make them better, any deck can be used. I know you're going for purely legendary, but maybe some glorious anthems to boost your creatures up a bit?
Other than that, I have no idea, maybe an Avacyn. I know the deck is supposed to have awful legendaries, but having a few good ones isn't bad right?

When I first started playing EDH with my friends, Jenara was my first ever leader. It was an Exalted Bant deck with a little emphasis on counters and doing whatever I could to keep Jenara and other creatures safe. My main opponent was a r/b Olivia Voldaren. Kept taking my creatures, but he'd never touch Jenara. I'm happy to see someone else using her again. She's a really good creature and leader.
I like the idea behind this deck. Maybe you could add a Hunger of the Howl Pack. Should do nicely if you ever plan on adding more counters to things. Keep up the excellent work.

Insidious Bookworms is basically a Drainpipe vermin with a higher costing death ability. Worms of the earth is such a late game card that it would hurt me more than it would hurt my opponents. It also wouldn't help shrieking affliction at all. They'd keep the lands in they pull in their hand and that would build up their hand. Cabal Interrogator is actually decent, but I don't know if I'd be able to find any since he's such an older card.
Thank you for suggestions. If you see any other things you'd like to change with this deck, or any other, please let me know!

Spirits are really tough to work with. Most of them are overpriced for the little that they do. If you have any suggestions to help this deck run a bit faster, please let me know. Thank you.

Instead of Stormbound Geist, why not add Sky Spirit. Similar drop, but Sky Spirit has first strike and can block creatures without flying.

The only thing I could advise for the deck now, would be some more dual lands that aren't gates. Gates are awful unless you're using a gate deck. Try Glacial Fortress or Drowned Catacomb.

For Daishi.
This is what I meant when I posted that comment to your deck. I really liked the idea behind it, I just thought that I could use a bit of a tweak.

Why do you want to add Jace's Mindseeker?
That's really a conditional card.

Alright. So I've looked over the deck, and I love the idea of super counters. I would recommend, however, that you try and get some consistency with the deck.
Add more of Putrefy, Golgari Charm, Burst of Strength, CorpseJack, Slitherhead, Scavenging Ooze, Gyre Sage, Abrupt Decay, Experiment One.
Actually, since I have so much I would like to change, I'll remake the deck for a minute and show you what I would like for you to do with this deck. If you like it, great! If you don't, no harm done.

Remade the deck with what I would change:

Mycoloth and Thromok are so incredibly broken. I don't know why Wizards gave the go ahead to those cards.
Anyway, Voracious I thought about, and he just felt off to me. I don't know. I feel like he'd be more at home in a full goblin deck rather than a devour deck.
If you can think of something to take out for Hellkite Hatchling, I will gladly add him in. I'm no good with the whole switching around cards and replacing them thing.

Ah. I see. Didn't think about the combo with Door of Destinies. Very glad you have it in the deck. Umm... I know there's an enchantment that lets you buy 5/5 dragon tokens. Not sure of the name.
I'm not sure how you feel about your mana curve, but you could always throw in some Rage Reflections or something that gives your creatures double strike. Can win you games if your opponent is defenseless.

The Voracious Wurms are there for low drop defenses or late game low drop big creatures, if I have Trostani out. I took out the Worldspine Wurms and threw in some Rampant Growths to try and speed up the mana ramp and drop the curve a tiny bit.
How does it look now?

Add Lazav, Dimir Mastermind. He can copy things. Also Cryptoplasm is basically a low drop Clone that works without a Cloudshift.
I have a clone/mill deck on the site currently. If you'd like, you can check it out, maybe get some ideas from it.

Why do you have Arcane Sanctum and not Isolated Chapel?
Everything else in the deck looks fine, but you may wanna drop Sigiled Paladin and put in Duskmantle Prowler, or Servant of Nefarox, or Battlegrace Angel or that wouldn't run you two whites in the beginning of the game. I feel as though it would throw off the fluidity of the deck.

Why is Zur the Enchanter even in this deck? You only have like 4 enchantments he could even bring out. Why not add something that'll actually help the deck, rather than just throwing some random legend in it?

Well... This is an interesting idea for a Token deck. Normally, I'm not a fan of populate, but you've made it seem like it'll work wonders with this deck.
My only issue with the deck, is that I would put in some Chorus of Might to give Wayfaring Temple Trample. The one thing I hate is when someone just chump blocks with a 1/1 saproling and I don't get to populate.
But anyway, you're deck. Do as you please.

I like the idea behind this deck, and the only things that I would say to change is Braid of Fire and Dragon Archwing. I know it sounds like the mana sticks with you throughout your turn, but it unfortunately doesn't. It phases out as soon as your upkeep step ends. So maybe other cards that give you red mana like desperate ritual. I knew some off the top of my head, but I can't think of them now. As for Archwing, he's a low drop sure, but he goes back to your hand as soon as he done. If your opponent has a defense that can withstand him or worse, take him down, he's basically useless. Maybe something that makes your dragons cheaper to bring out like Dragonspeaker Shaman? Burn spells can also help if you just can't seem to break through the enemy's lines.
Good idea. Improve on it and this will be a nearly unbeatable deck!
