Reading the Card Explains the Card.

Stop getting butt hurt when someone says this to you, the phrase literally answers all of your questions by asking you to re-examine the card you're asking questions about.

See that card above? Someone asked, "What is this card's color identy?" I'm sure you have eyes and can see the blue, black and red mana symbols on the card right? That means this card has a three color identy, despite it being an artifact. I do not know why people have such a hard time with color identy, or say really how any card actually opporates within the confines of the game, as though these things are somehow not readily unstood by just comprehending what words mean and associating them with the things that they interact with. When someone tells you to read the card, they're not just being an ass hole, they're trying to get you to think. So put your big non-binary pants on and do what everyone else has down while playing magic; fucking read.

Grixis Control in Historic Brawl.

I play Nicol Bolas, The Ravager as my commander in historic brawl, here's my deck list:

I could spend a couple of wild cards and get the R/U Zendikar lands, but what I've got right now kind of works just fine. The way this deck wins is mostly through an overwhelming board presence where I stop any and all attempts from my opponent to regain control. 

Secret Tech: I love throwing Spark Double in the Graveyard as a little bonus for when I manage to flip Bolas, because the only thing better than having one Nicol Bolas, is having two. The thing about Bolas too is, even if you cast it and it's countered, you're still getting value in the form of removing interaction your opponent could have used for something more impactful, bonus points if they let Bolas resolve and they burn a kill spell on him and still have to discard. The other thing I love doing is casting Sublime Epiphany, countering my opponents spells, bouncing a permanent, and drawing a card, only to flash in a gearhulk and do it twice. That's the peak of shenanigans.
