Amazingly Good & Fun Shitdeck feat. Niv (Standard)

So the idea of the deck is obviously to play Niv and get as many cards as possible out of the deck. Therefore i tried to play only 2-colored cards.
So let's talk about the cards in more detail:
Lands: I took all lands i have and put them in the deck. (yep, there is one shockland missing, but who cares?) Honestly the deck runs quit good with the Gateways and Spires, but is a little bit too slow for Aggrodecks most of the time.
Prowler: Is in for ramping and fearing the enemy because of deathtouch and lifelink, which helps a lot to survive.
Treasure map: helps ramping and card drawing. It does a lot of things, you know that.
Angrath's, Despark, Tyrant's, Spiral and Mortify: Should be obviously clear. They do what they should do.
Veto: I'm not a 100% sure, if it's the best choice. Maybe Absorb would be better for sustain, but the 2 blue mana could be a problem.
Brutality: Does a lot of Damage and kills x/2 creatures. So Prowler and Hostagetaker will survive. For the late game the card gives a tone of damage when combined with Invade the City.
Invade: The card that fears your opponent to death without them even knowing (knowone would thought erasure this one). Only makes sense to play after you have like 3 or more instants or sorcerys in your graveyard. Has a lot of synergy with Brutality and Niv, bacause you have most of the time to discard some cards after playing him. It's quit nice to have a 13/13 attacking or to brutality the shit out of creatures.
EtG-E (as i like to call it): 4 damage, 4 cards from the library and amass 4. it just annoyes people. Somehow I established a fetish on making people drop their God-Eternals without having them back. So satisfying. Not to forget that the Amass comes quit handy with Brutality.
Time Wipe: Saves your ramp or Niv while destroying everything. Kind of annoying aswell, because the opponent knows exactly that the Niv Train arrives again next round.
Storrev: One of the yet widely unkown cards. But to be honest it is annoying as hell. 4 mana 5/4 with trample and the ability to get back Niv, Hostagetaker, our Deathtouch/ Lifelink/ Ramp- Guy or Krasis. Which is pretty amazing.
Sphinx's and Krasis: For obious reasons. Drawing cards and getting life at the same time - annoyes mostly red-deck playing retards, but honestly it makes me feel good.
Knight: Kills stuff or heals, therefor equals to maximum annoying for red and gates (or other enchantment based decks). Now think about getting it back with Time Wipe. Destroying the confidence of your opponents right away.
Speaking of not only winning but destroying your opponent: I added my 2 favorite torture instruments.
Captive Audience: Most people can't really deal with it, but they think they can win anyways instead of just surrendering right away. Seeing them struggeling makes me happy (maybe i should see a therapist). It's a win condition and it works most of the time.
Casualties of War: Deals with everything at ones for just 6 mana. Kills a planeswalker, a creature, an enchantment, an artifact and a land at the same time. What a card! You can even feel the hopes and dreams dying inside your opponent. I'm kind of sad if the opponent is not worthy enough to play this card. I mean destroying just a creature and a land is kind of boring.
Justice Strike and Solar Blaze: Are quit good torturing cards, because they let creatures kill themselfs. But sometime they just don't help you because your opponent is so weak that he plays only with creatures with x/x+1.

What I think should be made better: The Deck is just thrown together because i got some Nivs and i felt deep inside that i have to build something annoying arround it. So i threw everyting in I had in 2 colors at the time and voila the deck was just amazing. It makes a lot of fun because of the card drawing and the fact that you play alot of different cards - improvising in the situation and winning with one life left is what keeps me playing magic after all. You will probably lose against people with strong and effincient meta decks. But who cares about those people anyway?
So if we could find a away to to put cards back from the graveyard into the library or hand, to ramp up faster or to draw faster, this deck will win even more.
Aswell sideboard cards are needed.

Thank you, and have fun!
