Sideboard

Vs. Red Deck Wins
-4 DOJ
-2 Keening Stone (Ravenous Trap)
+4 Leyline of Sanctity
+2 Ravenous Trap (unearth)

Testing vs. 2nd Place Japanese RDW
G1 - LOSS - Didn't draw a single archive trap or Leyline. Probably should mull more aggressively.
G2 - LOSS - Once I got a leyline things were going well, but then there was a land flood and not enough draw to get through it, and RDW was able to punch through with unearth guys.
G3 - LOSS - No Leylines, not enough creature kill. Unearth guys really hurt. 
G4 - LOSS - One Goblin Guide started wrecking me. This is sucking ass.
G5 - LOSS - Started with a Leyline, but too much gets through.
G6 - LOSS - Maybe was surviving before due to more Mana Leaks? I'm losing fast to his burn and creatures. Considering -1 Condemn, -1 Pitfall, -1 DOJ, +3 Mana Leak
G7 - WIN - Started with Leyline, had negates for the Earthquakes, enough PTEs, then drew a bunch of ArcTraps. This is how it is supposed to go.
G8 - WIN - Close game, life at 5 but had the negates when needed and Walls to block Goblin Guides.
G9 - WIN - Blowout victory, Leyline, plenty of spot removal, and a Jace ultimate followed by ArcTrap and RavTrap.
G10 - LOSS - Decked a bunch, but an unearthed Hell's Thunder and a few staggershocks (no Leyline) did it.
Total - 3 Wins, 7 Loses. This deck, with lots of haste and unearth creatures, is pretty much too fast too race. Possibilties include Mana Leak to slow them down or Kor Firewalker (but that would be really narrow).
To add 4 Mana Leaks, would need to remove 2 Pitfall traps (fine, limited use against unearth and most decks anyway) and maybe Mysteries of the Deep or something? Maybe -1 TrapSnare since, awesome as it is, in many matchups it ends up sitting in hand for a bit?


Vs. Planeswalkers
- 4 DOJ
- 4 Pitfall Trap
- 1 Wall of Omens (they're usually pretty useless, can side out more depending on deck)
+ 2 Leyline of Sanctity (nerfs some walkers)
+ 4 Oblivion Ring
+ 4 Pithing Needle

G1 - LOSS - They had 1 card left in library after 2 Archive traps. A celestial colonade pumped by Elspeth hit three times for JUST enough. Next draw was a condemn. 
G2 - WIN - Controlled the game, Negates were key vs. Planeswalkers, ArchiveTraps did their job, if not for a big martial coup it wouldn't have been close.
G3 - WIN - The same, dominated except for a Martial coup, got me down to 2.
G4 - WIN - Awesome. They got in a few hits with a celestial colonade, but I drew a Path before I went below 12. I like having 4 Trapmaker's snares a lot. They had Ajanis in hand but couldn't get the Mountain - without fetches their mana gets really rough. They would have lost even quicker if they activate the ArcTraps though.
G5 - LOSS - Had a hand full of PTEs, but three spreading seas kept me from getting a single plains, then Gideon and Colonade did me in despite Jace's ultimate going off
G6 - WIN - Martial Coup got some damage in (one was Netgated, but they had another) but an ArcTrap and then a Keening Stone did the job.
G7 - WIN - They had 3 walkers out at once and really put the pressure on, but ArcTraps and Keening Stone at just the right time got there.
G8 - WIN - Big game, both sides had a lot of land and spells. Critical to Negate Martial Coups.
G9 - LOSS - A martial coup put the capper on it, but it really was just too much path and land draw. They had three planeswalkers going at once and Jace's fateseal screwed up my draws.
G10 - LOSS - A single soldier with Elspeth booth. Not enough answers drawn, kind of land flooded. Could have decked with next two cards.
Total - 6 Wins, 4 Loses. This definitely seemed like a better match-up, with most games wins or very close. Mana leak would have been less useful in this match-up, but could have stopped some killer coups.

Vs. Eldrazi
-3 Keening stone or whatever (depends on deck type)
+3 Ravenous Trap
