Well, I really like your deck, it's fast, strong and hard to kill. I had a really tough time against it with my aggro golgari deck. It's rare for my deck to have that much of a hard time against another deck that I test, but your's really know how to kill mine.

I feel like the only thing that I could say is that I don't feel like the black is adding as much as it should. I think that you could keep it mono green by adding your maybeboard into the mainboard instead and the deck will be just faster and more consistent.

There is absolutely no doubt in my mind that your deck deserve a +1 from me !!!

I definitely think Ulvenwald Tracker deserves a spot here. He is so unfair when a Predator Ooze is on the field.

Definitely stay golgari. Putrefy and Abrupt Decay are two of the strongest creature kill cards available

Strangleroot Geist needs to go. A good replacement would be Deathrite Shaman

If you're going to have a lot of ramp cards in your deck such as Gyre Sage and Arbor Elf , then you may want to focus on having larger multiples of your bigger cards. Running three instead of two will really increase your chance of drawing the card.

Your sideboard is all over the place; substituting a single card instead of multiple of said card is merely gambling. 1/60 chance? Why not have three of the card instead and increase the chance to 1/20?

Interesting thought on the ramp / bigger cards. I'm not sure if it's the right approach because I'm only running 21 lands, but I'll have to try it out and playtest. We'll see how it goes.

As for the sideboard, the reason for that is that my meta-game here is very complex and evolved. There are tons of different decks to go up against, and I need to have an answer for all of them (even if my chance of drawing it is 1/60). The sideboard quantities are made with specific substitutions in mind, e.g. 1x Burst of Strength can replace 1x Bioshift against certain aggro matchups. Another example is Glaring Spotlight which I never ever want to draw 2 of in a single game. I'd rather open a valuable sideboard spot than risk that chance.
