(11/17/2017) Fireball's damage is divided as Fireball resolves, not as it's cast, because there are no choices involved
Grixis combines red, black, and blue in what is commonly called a shard. These three colors allow for a weird mix of chaos and control strategies, upsetting your opponents' games while keeping your own on track as much as possible
Use a paper cutter, a straight edge, and a sharp blade to cut out the cards carefully
At this point you can invest in cards like Ashe, Princess of Dalmasca, Combat Tutorial and Adventurers Airship to help keep your hand fueled, and even more cheap interaction like Youre Not Alone, Ice Magic and Syncopate to force through the win
Our best bet is to deny them enough lands to flip Den Protectors or cast Wingmate Roc or Gideon, Ally of Zendikar
I also have a soft spot for Nezahal, Primal Tide
