I've been playing a Conjurer/Illusionist and I love it. I primarily use Dremora Lords. They are incredibly powerful and will take down everything. Once you get Master Conjuration, they cost pretty much nothing to summon, unfortunately there are no Permanent ones. I found the Atronachs to be less then useful. They die really quickly to Dragons and their attacks are not very strong, although I only speak for the Flame and Storm. I also use Dead Thralls, and I started doing that at level 47 so I missed out on a few. My suggestions for thralls that you can get will be below, and I will only list those who I have found to have permanent bodies, meaning that if you don't visit their bodies often enough, they will still be there. I have 5.
But yeah, dragons are the only problem I have with this Build. My only direct damage comes from a bound sword which I have no perks in one-handed. So I have to use summons against them. I haven't tried any dead thralls yet, but Dremora lords are so far the only thing that can handle them. Granted, fire draongs take them out pretty quickly and they do get eaten quite often. But since the cost of the spell is so little when you get all the cost reduction stuff (Especially if you are a Vampire with Necromage wearing Arch-Mage robes and Vokun (the dragon priest)).
But yeah these are the Dead Thralls I have found useful and that have permanent bodies (so far from what I can see):
As for working Conjuration with Illusion, there is a plethora of options. When you get the Illusion perk Master of the Mind, you can dual cast Rally on your summons raising their Health and Stamina. Call to Arms does more raising, but you can't dual cast it and therefore can't use it on higher level npcs. I highly suggest becoming a Vampire if you use Illusion. You can cast the spells on everything but Dragons. Vampirism also boosts the effects of EVERYTHING from Enchantments on pre-existing items, or those you make, to special abilities and Standing stones. It is one hell of a powerhouse. But another thing Illusion works well with is you can summon your creature of choice, Muffle and then use Invisibilty and let everyone fight for you and no once notice you. Or you can shoot Frenzy into the crowd and just watch everyone slaughter each other. It really is only limited to your creativity.
But I will say right now! If you choose conjuration and you only want permanent thralls, do NOT get dual casting. The thralls are permanent and the dual cast doesn't affect it. BUT, if you plan to use Dremora lords all the time, get it. A Vampire with Dual Casting and Necromage can summon the Lords for a lengthy 6 minutes. That is incredible. And the fact that they barely die is a plus.
Hope this helps. I spent a lot of time looking into this particular build and it so far has worked wonders. If you don't want to be too overpowered, stay away from the Dremora lords, but remember, they may be your only chance against dragons.

Spoiler
-Orchendor: Pretty much everyone's favorite Thrall. He has an awesome teleport move which seems to heal him and uses frost spells and wards. You can get him through Peryite's Daedric quest "The Only Cure".
-Velehk Sain: To be honest he svcks, but he is a secret character in the midden that is in a quest that doesn't get added to your journal. Some glove and stuff. Just go to the Midden Dark and you will see for yourself. He has a unique hammerfell garb and a scimitar, but is overly useless. Has a permanent body.
-Sild the Warlock: Another great mage. You find him in Rannveig's Fast. Watch out as he will launch fireballs like mad.
-Illia: You find her at Darklight Tower. She actually is a follower for you if you do her quest, so if you don't want to kill her outright, she will help you. But once she dies, don't forget to raise her. I killed her outright. I'm not a fan of followers.
-Naris the Wicked: He is found at Morrvunskar. Another great mage.
I seem to only recommend mages because melee thralls get killed quickly. Do a google search of permanent corpses and you'll find others as well.-Orchendor: Pretty much everyone's favorite Thrall.

Thanks for all the great information and tips! Dremora and thralls...so much to try out! I suppose i should get into enchanting a bit so i can lower the magicka cost? I've always wondered how much Magicka i should have compared to Health and Stamina. This is great. It has given me lots of ideas. Thanks again.
