Terror In The Swamp

Few weeks I am new to magic and I went to the magic / tcgplayer.com look at some maps. I have some knowledge of maps and bridges, so I decided to make a deck that ran along most of the cast, but looking at it, I do not know. Is it good? What do you want to remove / add?


Plot:

Swamp x20


Spells:

Contaminated Bond x4
Demon's Horn x2
Distress x4
Mind Rot x4
Rain of Tears x4
Raven's Crime x4
Yoke of the Damned x4
Terror x4


Monsters

Nekrataal x4
Nightmare x2
Nyxathid x4
Ravenous Rats x4
Ogre Marauder x4

It is decent, especially if you say your just beginning, however, what you should consider doing definatley throw in another color. If you play I'd throw that color blue. If you use blue, you can also use Counterspell very powerul as Ambitons Broken, collecting samples, Counterbore, and Cryptic Command, which would help you to say your opponent had something to play. I would also throw in the cards as the Helm Ghastlord, Ghastlord of the fugue, trauma, Glen Elendra Liege, Jace Beleren and hypnotic Spector. Also, you should get some non-basic lands like the ancient ziggurat, underground river, and Terramorphic Expanse. Once you get better, if you play as Blue Black Deck I highly recommend Red like to add a third color so you can play the piece Grixis to your advantage. Then you would be able to use the cards as Sedaxris Spector, and Nicol Bolas, surveyor.

I seriously suggest to add more land. She knocked on at least 22, preferably 24 to draw reliable. Also, I suggest taking the yoke of the Damned. Replace them with the move as more reliable Shriekmaw (which also increases the number of your creature), or sudden death comes as the strategies of individual tubes (in this case, Counterspell or leaving response).

Otherwise, the bridge looks excellent. If you Abyssal Specters, those who really add to the deck and keep the legal standard. If you do not need to keep Standard, support would be a big plus as well.

not bad at all. first couple of things I would leave bond is contaminated, horn demons, the rain of tears and yoke of shit. winning isn't life that matters in a game in black making them lose their life is what you want to, destruction of land can put you behind as well as the setting behind, it could become more relevant in a game late. and the yoke of shit might be too slow if you need to do now that creature.
some cards that could be replaced
Spells
3Unmake-BBB remove target creature from the game
3Corrupt target player loses life-5B equal to the Swamps you control, and you gain much more than life
creatures
4Hypnotic-1BB Specter 2 / 2 flight, whenever hypnotic specter deals damage to an opponent they discard a card at random (which is devastating)
you can also add two more land in this case, you can subscribe
A defeat and a nightmare. nightmare is good, but corruption is much better. you turn right difference of 12 points when you play with corruption and if you use spectrum hypnotic then you have a threat of theft at the beginning of the game to take hits in their lives, more nyxathid is also potentially more relevant then nightmare because it falls earlier and grows rapidly
