Glad to hear it! Thanks for reading.

It would help to know what colors you plan to play to give you specific cards to help with mono black.

Sean has a great list here. The article above with spot removal (Path to Exile, Swords to Plowshares, Condemn, Unsummon, Rend Flesh, etc) seem like great places to start. If he is crushing you with the general, then find ways to put his general in the deck. Hinder is probably my favorite way to do this.

Akroma's Memorial is an artifact that, among other things, will give all of your creatures pro-black.

Black has a host of nasty enchantments that can really mess with the board. Mass removal of enchantments works really well when one player goes over board with enchantments. Primeval Light is a card that will suite you well.

If he ISN'T running Phage the Untouchable, try Telemin Performance. It mills their deck until they hit a creature card and then that creature comes into play under your control. 12 is really great odds you'll hit at least 10 cards. This plus Relic of Progenitus will give you some great mill/graveyard removal.

The other thing to do in this situation is to form a play group that doesn't involve that person. If they are so dominate that they cause people not to want to play, exclude them from your games. After awhile, they will change decks and hopefully they will learn how to be a productive member of the community.

If you are looking for more help just look me up on twitter @hawtgnutek . Best on ya!

Probably the worst card I can think of that a deck like that would run would be Death Cloud. No fun at all. Maybe mass discard as well.

So, try some things like this:

First, spot land removal. Wasteland may be expensive, but Strip Mine, Ghost Quarter and Tectonic Edge are cheap, and you can tutor them all up with Tolaria West or Expedition Map. Pack them so the mana doesn't get out of hand.

Flashback spells are great, like Ray of Revelation, to take care of things like Grave Pact or the like. Additionally, War Priest of Thune and Duergar Hedge-Mage are awesome.

Finally, if there's one permanent type that will give a black player headaches all day long, it's enchantments. From Leyline of the Void, Leyline of Sanctity, or even just Mobilization, you're looking at some difficult to deal with protection. Asceticism and Privileged Position will give his targeted "answers" nothing to target.

As far as threats, look for things that are resilient and give you value even if they are dealt with quickly. Additionally, protection from black is pretty sweet, especially on cards like Akroma, Angel of Wrath.

Fantastically, there's an ENCHANTMENT (ding!) that gives ALL creatures protection from black. You're sure to gain some allies against this guy with that card. It's called Absolute Grace. Watch him squirm! He can't even target his own guys. Non-creature artifacts have a history of causing black mages grief, too. Akroma's Memorial fits the bill AND gives your creatures haste, which is a great way for them to have some fun before the Damnations and Living Deaths take care of them.

Auriok Champion and Chameleon Colossus are pretty sweet, too (and they would be even without pro-black). Devout Lightcaster does two things black doesn't like: laugh at Doom Blade and exile their stuff! Mirran Crusader's double strike is awesome with equips, and as a bonus he's pretty cool agains elves, too!

Speaking of which, there are two excellent (if pricey; hopefully you have a copy or two in your collection) equipments with protection from black as a perk, but certainly not the main point: Sword of Feast and Famine, and Sword of Light and Shadow. The latter, combined with Sun Titan is _stupid-hard_ to get rid of. Kill the sword? Oh, look, it costs 3! Kill the titan? Something else swings in (Soltari Monk? Stonecloaker?) and brings him back to your hand for more.

Stonecloaker and his big brother Dust Elemental are pretty sweet insurance against removal, too.

If blue or green is more your thing, try Master Transmuter (now you see it, now you don't!) or if Green is better, Great Sable Stag and Whirling Dirvish.

Also, check this sweet combo: Karmic Guide plus Cloudstone Curio! You'll get a creature back every turn for 5 mana, and return your Karmic Guide to your hand where it will survive most things Black can cook up.

Finally, punish swamps! Crusading Knight will put the hurt on quickly. Karma, as they say, is a b*tch. So is Kormus Bell plus pyroclasm, or Roots of Life!

Go old-school when color hate was cool. Lifeforce is an answer to all sorts of swamp-flavored problems. Heck, so is Nightsoil, to some extent (since it hates on creatures in graveyards, but that's less of an issue if your "friend's" deck is light on critters.

Hope that helps!
