I really like Ashiok, Nightmare Weaver and it fits this deck style. It's not super expensive, but it is more than $5.

Underworld Connections could help you draw into more ways to steal their stuff.

Baleful Strix is one of the best UB cards for commander.

Otherwise I love the deck! Keep it up!

Oh yeah, and Mulldrifter is pretty awesome too. Try it out!

How do you end up commenting right after me whenever I post in that thread? Are you like a psychic or something? Lol

Actually, Ashiok, Nightmare Weaver would go great in this deck. Sadly she can only hit creatures that she exiles, but that's still pretty damn beneficial especially in an explosive format like EDH. I'll take those others into consideration too. I really like the idea of Underworld Connections, especially when you take into consideration the fact that for a U/B deck, I have remarkably little card draw- just Dictate of Kruphix. I may add Howling Mine and Font of Mythos as well.

Considering the theme I'm surprised you don't already run Beguiler of Wills. Another great card that kind of fits the theme of the deck is Havengul Lich

Two cards that I actually don't own... Lol I wasn't playing much during Innistrad block so a lot of the clone/steal cards from that block, I just don't have. If I get ahold of them, they'll definitely go in. Thanks for the comment!

Your welcome, and its a good thing those cards are pretty cheap. I really love the deck because I also have a deck that likes to borrow my opponents stuff, except my general is Sygg, River Cutthroat.

My suggestion to steal your opponents creatures is the amazing blue card Willbreaker Target your opponents creatures with any spell or ability and then they are yours!

Willbreaker is amazo in decks where I actually have a lot of ways to target my creatures. Sadly, this deck really doesn't fall into that category. If I do end up including more target effects, the Breaker will definitely go in.

Excellent idea. +1.

My only suggestion off the top of my head is Keiga, the Tide Star. Only a few bucks and a nice heavy hitter. Plus if you can figure out ways to reanimate and sac him (which is possible with your color scheme) he'll have multiple uses.

Though its making room for that stuff that will be a challenge.

Actually, there's really no need to reanimate him. I can always just slap a Followed Footsteps or Mirror Mockery on him and fulfill the exact same need. That is a really good idea, I'm going to have to find a way to work him in. Thanks for the suggestion and +1, smiffdemon!

Ha! Even better :D. No problem! Id love to play against this deck.

Control Magic

Keiga, the Tide Star

Desertion

Clever Impersonator

Deadeye Navigator

Rite of Replication

Phyrexian Metamorph

Evil Twin

Body Double

Sepulchral Primordial

Dimir Doppelganger

Stolen Identity

Here is a mixture of good and budget cards...

Here are the cards you mentioned that are already in the deck: Control Magic, Keiga, the Tide Star, Clever Impersonator, Rite of Replication, Phyrexian Metamorph, Evil Twin, Body Double, Dimir Doppelganger, Stolen Identity

Now to address the others individually:

Deadeye Navigator- Hmm. This one merits further testing. Being able to blink my creatures at instant speed to dodge removal and possibly have them ETB as a different creature if I need it to, is a hell of a prospect. Plus I know I have one, as I just got it the other day. So yeah, this one will probably end up going in there.

Desertion- This one is nice too, albeit a bit on the pricey side. If I decide to expand the deck a bit more into the expense territory, this one will be near the top of the list.

Sepulchral Primordial- Reanimation is my favorite thing to do in Magic, hands down. This may end up in the deck if I find there are lots of creatures in my opponents' graveyards that I want, but can't get my hands on any other way.

i like Ashiok, Nightmare Weaver from your maybe. nice job here +1!

-1 Jwar Isle Refuge, +1 Ashiok, Nightmare Weaver (thanks to hateindigital for the idea)

-1 Island, +1 Deadeye Navigator (thanks to Adam_Kaiser1 for the idea)

-1 Dimir Signet, +1 Vesuvan Doppelganger

-1 Eye of the Storm, +1 Desertion (again, thanks to Adam_Kaiser1)

-1 Split Decision, +1 Gather Specimens (got it in a trade with ducttapedeckbox and I figured it would make a good home here)

I love clone decks because they're only as good as the deck you're playing against. I only took a quick glance but I do have one suggestion: replace Thrax as your commander with Marchesa, the Black Rose. She gives you the ability to get your clones back so that they may copy something else if they die.

I would agree with replacing your commander. Thrax seems to be more of a figure head than helping push the deck toward. Over all, cool deck! +1

I already have plans to replace Thrax. I was leaning towards Sedris, but I agree Marchesa would be a much better Commander. Thanks CastleSiege and michael921!

You sir, are a dirty dog. Lol This looks like a lot of fun to play. Did you consider Dack's Duplicate?

Huh. I must have derped pretty hard not to remember that card. I had it in a previous iteration of the deck that had Melek, Izzet Paragon at the helm, but it must have slipped my mind on this one. I'll definitely add it in, thanks!

Hey there, just saw that your making the same kinda deck I am, with Marchesa. Mines not complete yet but here are some thoughts to consider. Blatant Thievery-take control of one permanent per player. Rise of the Dark Realms this is a bit on the spendy side so i dont know, it would b fun tho ;) Beguiler of Wills -pretty much take a creature each turn. Dominus of Fealty. Empress Galina- THIS IS A MUST!! take their commanders...indefinitely Lord of the Void-not only exiles their deck, u also take something. Olivia Voldaren this is right on that budget, if u say yes, make creatures into vampires, steal vampires. Riptide Entrancer. Sphinx Ambassador this is tons of fun, read it. Thalakos Deceiver . Sepulchral Primordial. Aura Thief- take all enchantments.

here is some of the cards i have that might be towards your liking. most of these cards are within ur budget, a couple are just above it a smidge. and yes, i like ur strategy, i think its fun. i originally want to make a marchesa deck cuz i wanted to run all the Swords, still doing that, but i found how fun it can be to take other peoples stuff
