Lol look at you go man! It's great how many of the same improvements we have made in the last few months without knowing. Love seeing this again to find you also sided A LOT of the same things I did!

I did come to find that Apostle's Blessing is not as useful as some other counters such as Turn Aside, and I recommend that instead. I'd also take out Gitaxian Probe and Serum Visions... the Probe is not useful in competitive play, when it is better to just focus on aggression and setting your loop than on keeping an eye on their hand. It was once one of my favorite party tricks, but now it's out completely. I also sided and experimented with 2x Extirpate, but since you use it after something of theirs is countered or hits the grave and they are almost always tapped out, they never seem ABLE to counter Surgical Extraction anyway, so it is just overall superior.

This thing is looking really good, but I'd recommend having a shared look at my Mill and Torture sideboard for a few things that really ruin the meta for other decks, allowing us to get our loops off. Sweet deck, man.
