Nemesis of ReasonWall of FrostMind GrindWaste Not - and other cards similar to it.Cyclonic Rift

Things to remove-

You can remove jace, mind architect cause it's bad. Put another big butt creature, or utility card in there.

Mental Vapors ?? why lol. Your general does that for all your creatures. This is a wasted slot. Put in mind grind for this. Small mill effects are crap especially when you can already do it.. it's gonna mill only for one... all of your creatures can already mill for 1 or more with phenax. Also it's TARGET OPPONENT... so 1 card off one person in commander is poopy. Anything I posted above should go in for that.

Rise from the Grave... so many better cards than this. SO MANY... Geth, Lord of the Vault is 1 more mana... and is a 5/5... with evasion. So you can use it with Whispering Madness, also he's a 5/5... so at least mills 5, and can also use his ability to steal creatures... AND ARTIFACTS from opponents graveyards. Or just go with a simple Animate Dead.... so much better.

Vedalken Entrancer again to slow and poopy. It's 1 person.. and he's 4 mana to come in.. for a crappy card. DO some mana acceleration, card draw, or something else for 4 mana. Or add a better creature with utility. I'm fine with utility creatures, but not crappy ones like that. Just cause you are dumbing down your deck for your friends, doesn't mean you should have cards that are plain bad. Paying 2 mana when you can just tap him by himself to mill 2 to your opponent already without paying mana to do it...and he costs 4? For in essence.. a vanilla 2/2 because of reasoning above... why?

Stymied Hopes - get Counterspell better in every way even for the extra blue instead of colorless.

Memory Lapse - >.> same thing as above.. there's better counter spells out there and are cheap. Dispel Countersquall Swan Song Deprive Dissipate Dissolve. All in essence better counters in edh. In EDH removing is better than tempo type cards, especially when it's exiled.

Trading Post ... this doesn't belong in your deck, and you are only gonna use it as a goat producer.. There's better things that can produce tokens in blue and black if that's what you wanna do. This card is bad in your deck.

Undercity Plague To slow, and way to high costing.... in edh multiplayer for only 1 PERSON....remove it for something better. You are in U/B get some Windfall type effects, or more bounce, you also need more sweepers in general.

You should be playing some clones. Phyrexian Metamorph and essentially other cards similar.

There's nothing wrong with having actual card synergy in your deck even if you are purposely lowering the power of it. Playing plain out bad cards is never an excuse unless you are brand new to the game, and are learning. There's plenty of budget cards you can get or trade for that are just plain out better. There's a lot of cards in here in general I feel shouldn't be in here. You also will want to add more big butt creatures, and possibly some utility creatures.

You also need card draw, and more card advantage, Blue Sun's Zenith etc etc. You could use more ramp too. You are playing blue black control, and black and blue mages love them some mana and card advantage.

Also the suggestions box didn't show all my suggestions, so look through here cause a few won't show up in your suggestion box. Like Phyrexian Metamorph, which should go in.

Vedalken Entrancer sorry I said you can tap him to mill for 2.. when I meant 4. He's a 1/4 not a 2/2 so he's worse than a vanilla monster for 4 mana. Either way bad card, find something else. Maybe Trinket mage? Then you can get some artifact lands as well.

Thanks KillTheIslandUser! If you were wondering why there is so much junk in here its cuz i spent about 20 minutes making the start of it then I threw it on here to get some suggestions. all the cards in maybe I will get for sure. Just wondering Why Waste Not? not running a lot of discard, so it would be kind of dead.

All the cards you mentioned were cards i knew were junk, just didn't know what to replace them with at the moment. Thanks Again!

I said waste not because you should be running more discard type cards. Windfalls and the like. you are in blue black, you want card advantage

It was also just an idea, for something with whispering madness. You don't have to, but mill and discard usually needs to be played together. Just milling doesn't do much in it's own, you need hand disruption as well.

so should i run Despise, inquisition, etc? KillTheIslandUser

If this was a heads up sure, but as it's only targeting one person, it's not beneficial. The only difference is if you play cards that steal people stuff, like big game combo pieces that can help you win. But cards like Thoughtseize and such don't have a big enough impact in multiplayer.

If you play hand disruption you gotta play whole table ones. There's like 4 in blue, and 2-3 in red.

There is one in black though.. I forgot it's name.. that one is ok. As it can remove their whole hand, and I believe it does dmg to them as well. It's black and x, and for each mana spent into it, it removes a card. That one isn't bad, as it removes more than 1 card, and does dmg. And if you play cards like geth, you can get worth out of it, or other cards that take stuff from their graveyard.

You also don't have to run waste not if you don't want to. If you only will use a like 1-2 hand disruptions. Then yes it's not worth it. There's numerous ways to abuse it though in blue/black, but if you mostly wanna mill then that's fine. That being said, a little bit of hand disruption is still needed in mill.

Eater of the Dead mills a ton if your opponents play enough creatures.
