Since I don't see that much love for Nin, I posted my deck so you can tell me if I missed some good card and btw add it to the database for more Nin decks ^^
Nin is really cheap to cast and her power is really good. You can use it to reload your hand, kill a creature without drawing too much hate from the owner, and since she's 1/1, no one will fear to be killed by her.
Niv-Mizzet, the Firemind + Ophidian Eye: Everyone know about this, I'm just playing with Ophidian Eye since you can stop the draw and play it with flash.
Time Warp + Izzet Chronarch + Splinter Twin: Infinite turns, the combo can work with a lot of other cards, such as Sakashima, the Impostor, Kiki-Jiki, Mirror Breaker instead of Splinter Twin, etc.
Psychosis Crawler + Nin, the Pain Artist: Target, draw and deal some good damage to your opponents and get a beefy dude.
Stuffy Doll + Nin, the Pain Artist: As above, but you can only deal with one opponent.
Pestermite + Kiki-Jiki, Mirror Breaker: Everyone know about this one too, so no need for more explanations.
WTF no counterspells: I really don't like counterspells in Magic so I won't put any in my deck, and if you get counterspelled, you still get some ways to manage it with all the copy/redirect stuff.
No Reliquary Tower: The main reason is that when you start to get a lot of cards in your hand (And it will happens), everyone start to focus you so keeping 7 cards max in your hand won't draw too much attention. The other reason is that you need to discard some cards like Ulamog, and can't otherwise.
Copycat: Since you're playing a multiplayer game (let's say you're 4), you only have 25% of the best cards, so if you can copy the 75% remaining it's better, plus you won't play agressive cards so you won't get focused in the beginning. In the end you can just copy your costy spells if needed.
Dominus of Fealty: To get rid of indestructible things or planeswalker, he's good, and with Nin you can catch one of they're creature, kill it and draw ^^
Price of Progress: Really hurts decks with 3+ colors in it, and can be copied for moar fun.
