After sleeping on the results of the weekend, a few things I noticed, in no particular order;

Ancient Grudge might be good enough to side board again: With all the affinity as well as the increased popularity of stoneforge mystic (as well as things like jitte in some rock lists) ancient grudge might find its way back into the sideboard. My original list almost a year ago ran one in the sideboard, and it was pretty cool, but after a while I was just like "I would rather have null rod" and so I made that change. Only problem is with collar and explosives, you don't want null rod out at the same time as those. So ancient grudge will work it's way into my sideboard somehow. Probably in place of a grip, which recently has been very underwhelming with the lack of counterbalance. Also, ancient grudge is good at getting rid of pithing needles and chalice of the voids, while null rod doesn't quite do the trick.

Life from the Loam most likely deserves a spot in the sideboard: As wweenieking attested, the card is sweet against deck where wasteland can take them out of the game. As well, it gets around discard and permanent destruction, which was the problem with crucible. I really wish that I could of had one in my top 8 match saturday when I played against 12 post, although I sadly wouldn't of even gotten a chance to use it since I had a deck reg error and got a game loss, followed by losing game "2" and not getting a chance to sideboard ever. LftL is also good against midrange decks like junk where a loam and wasteland can keep them off mana so long as you save stifles to deal with their fetches.

Pithing Needle is very solid out of the sideboard: When I gave my 75 to friendly Phil Stolze on sunday, I made the change of 1 null rod for 1 pithing needle to see how it would work out (all the affinity and countertop thopters from the previous day weren't there). I just wanted to see how effective needle would be, and Phil said it worked well in many situations. There was one game in particular where he was pretty much dead on board to a dark confidant equiped with jitte, as well as TWO active moms on the board, but worked his way out of the situation by using EE to get rid of bob and the jitte, then seaching for needle and keeping the moms from losing him the game. I'm not sure if needle should find it's way into the maindeck, since there are plenty of times where I don't really need it, but I would really like to have it in the sideboard from now on. It would be especially nice to be able to have it against vial decks to give yourself a quick and easy answer to goblins and merfolk, and to a shorter extant death/green and taxes.

So with these findings in mind, this is what I'm going to have in my sideboard for the time being

3 Spell Pierce
2 REB/pyroblast
1 Krosan Grip
1 Ancient Grudge
1 Null Rod
1 Pithing Needle
1 Mind Harness
2 Gilded Drake
1 Life from the Loam
1 Relic of Progenitus
1 Tormod's Crypt

The flexible slots would be some of the REBs, the drakes, and the crypt. It pretty much depends on if you're confident there aren't many graveyard based strategies (better for smaller tournaments), if there is alot or only a little KotR in the room, and how much blue is being played. In all honesty, I really wish I could sideboard 16, since that would make things so much easier with the REB count moving back up to 3. For the time being though I'm going to try this configuation out and see how it works.

Also, one last side note; sorry greater_maro to hear about dragon stompy being the only deck you lost to in your tournament. For those of you who don't know, dragon stompy is actually one of your best possibly matchups, about as good as the belcher matchup. You removal kills all their dudes, their blood moons are really shitty against you (you can't play goyf but you can play every other spell in your deck, seems fine to me), and they have no answer to vendillion clique. All in all every card in your deck is fantastic against them, and after sideboard things just get more awesome. I've played the match IRL about 6 times or so, and every time it's been a 2-0 blowout, with none of the games being close. It's too bad magic is a game of variance, and even you can still lose to your 80-20 matchups once in a while
