Have you considered Ashen Rider instead of Angel of Despair? It's one mana more, but has an effect when it goes to the graveyard (as well as when bounced), and exiles instead of destroys. Also, what with the 15 creatures you have with 2 power or less, Reveillark may also be a pretty useful card. Also, I don't see much draw in the deck - would it be worth adding Sphinx's Revelation or Stroke of Genius?

Also, if you have the money for it, then a Palinchron would do nicely as a back-up for when something happens to your Peregrine Drake. It's a little more, but if you have that and any card that wants infinite mana (e.g. Mnemonic Betrayal) then you can some pretty awesome/awful stuff <(^_^)>

The Silver-Bordered cards and Bronze Tablet are largely cards I'm including for the fun factor. I like having Un-set cards sideboarded in case the game isn't necessarily too serious, and a bit of spice would make it more interesting. Bronze Tablet is not something I would use with anyone who isn't fine with the whole ante shenanigan. It was in my collection, and fit okay enough, so why not? As you might have noticed, I reworked the deck because I found that the prices were getting out of hand. Mnemonic Betrayal looks amazing, but considering it's a mythic in the most recent set in Standard, I'd like to wait for the mass box openings 'till I pick one up for a better price, or I'll trade my Deathrite for it and Praetor's Grasp. Bloodchief Ascension looks fun, might trade my Mission Briefing for it. I hold Magistrate's Scepter close to my heart because I have the promo version (one of the only two promos I own), and the threatening nature of it means I can divert attention away from my hand and towards the artifact. If I can find justification I'll cut it though. Spellbook is also a cut. Mastermind's Acquisition as well. Glasses of Urza (which I legit thought was an un-set card at first lmao) is useful utility early on but loses purpose after. I'll cut it. I appreciate the help lots!! Do you have any help for creatures? I'm only at 16 and it's kinda growing on me.

Okay, so I finally had some time to come by and take a closer look! First, I suspect you know this, but Crow Storm, Five-Finger Discount, and are silver-bordered and thus not legal in commander. Many playgroups will allow them, though, which is fine if yours lets you. With that being said, Bronze Tablet is beyond banned: it permanently exchanges ownership of a card, an effect that is never ever allowed under any circumstances in modern Magic. I know it's in the sideboard, but it's not even worth having there.

Second, this deck looks a lot better than the first time I stopped by here! It has a tighter focus and more focus on a specific goal: steal if you can, mill if you can't. You're still on a budget, so I'll do my best to keep that in mind. I don't know if you're opposed to infinite combos, but Bloodchief Ascension is great here: just a great card anyway with mill, but doubly awesome when it goes infinite to kill opponents with Mindcrank. Mnemonic Betrayal might be exactly up your alley, as might Lazav, Dimir Mastermind and/or Lazav, the Multifarious. You also could use some more decent draw effects, like Rain of Notions, Read the Bones, etc.

Beyond that, Mastermind's Acquisition doesn't function in EDH unless your playgroup is playing with unusual rules (the second mode just doesn't do anything). My first cuts would be Energy Chamber, Feroz's Ban, Glasses of Urza, Magistrate's Scepter, Spellbook, Mastermind's Acquisition, and Peek. I hope that helps!

Maybe Mnemonic Betrayal when having Thousand-Year Storm out would be fun to storm off their deck. Thinking of a Grixis Thousand-Year Storm build in case you havent noticed lol

How do you feel about some of the new GRN cards? We have gotten some nice new storm support cards and some interesting cantrips :)

And just in general how do you feel about Guttersnipe and similar effects?

Deoplo, yeah that's what I mean when I say "spent the game getting rid of" Mnemonic Betrayal is in the deck to recast the enemies spells.

Something you said in your "Reusable Cards" section:
"Mnemonic Betrayal, late game card that allows you to reuse all of the cards you have spent the game getting rid of"

Correct me if I'm wrong, but I don't think you get to reuse any of your cards. Isn't it only your opponent's things that you get to use?

Mnemonic Betrayal is a good mana sink and can be a finisher, plus it has a skelly to boot!
