Lost to a no-creature Bant Approach of the Second Sun deck match one due to me being greedy. I won game one, no issues. Game two I spent four mana activating my Wandering Fumarole to protect my Jace, Unraveler of Secrets who was at 8 instead of letting him take 3 (I really wanted the emblem next turn.) Wasting the four mana in doing so, I didn't have enough to win the counter war over the second Approach. Game three, he ramped quick and I, again, couldn't win the counter war. Since it was a creature-less build, I found a lot of dead cards in my deck even after siding. Fun fact: the first Approach doesn't have to resolve to qualify the game ending second Approach. The second, however, must resolve for the game to end.
I then had an extremely rough match 2 against a Grixis Control deck that was running four Fevered Visions. My hand was constantly clogged with creature/artifact removal spells. Once again, even after siding, I couldn't get enough out the deck. Nine cards in/out, I still didn't have enough in my SB to get all the creature/artifact removal out of my MB. It was during this game I realized I needed a lot more non-creature, non-artifact hate.
x1 Hour of Devastation > x1 Nicol Bolas, God-Pharaoh
I loved how HoD preformed, but I hated seeing it so often. This deck digs so much, I found them too often to keep them both MB. One got moved to the SB, and, now that USPS arrived (two days late), I get to test out my favorite MtG character.
SB x1 Chandra, Flamecaller > x1 Hour of Devastation
>I like Chandra, I really do, but I removed her for two reasons. First of all, my turn 6 play is, ideally, a Gearhulk. I do not want to tap out T5 for Jace/Scarab, then T6 for Chandra, and finally T7 for Nikky B. Secondly, I used her more as a board wipe. Drop her on T6, ult her for three, then continue on my merry way. Now, we have Hour of Devastation to do the wiping, and it hits a turn earlier.
SB x1 Abrade > x1 Negate
Less artifact and creatrue hate, more Negate.
SB x1 By Force > x1 Negate
I was too scared of artifacts. I would much rather just stop them from resolving, or stop whatever creature crews them. We need more flexibility, and Negate does just that.
SB x1 Thing in the Ice
Flip > x1 Supreme Will
I like switching Censor out with TiTi after G1, because he is the ideal T2 play. I'm only running 3 to switch with, and I want more counters in the SB.
