Round 1: He has Zur the Enchanter, Confiscate, and Copy Enchantment. Black cannot kill enchantments.
Round 2: He has 3 Call of the Herds in his opening hand. The next game, he has Stormbind. Black cannot deal with six elephants. It also cannot kill enchantments.
Round 3: R/W Storm is not a very good deck. I win!
Round 4: Creatureless Rack + discard is not a very good deck. I win!
Round 5: It's a mirror match, but I play stupidly.
Round 6: "Gain 4 life" is not fun for an aggro deck to hear in Standard. Also, black cannot kill Paladin en-Vec.
