The deck looks great!

This is the swap that you ended up allowing you to keep Verduran Enchantress...

• Chaos Warp -> Eidolon of Blossoms

There's nothing wrong with that adjustment. It's probably better anyways.

But if you wanted to add a removal spell back in, the best adjustment would probably be...

• Kor Spiritdancer/Sram, Senior Edificer -> Abrade/Unexpectedly Absent

Sorry I make so many edits...

**Edit: A more aggressive option for this slot is most likely better if you decide to make the change...

Kor Spiritdancer/Sram, Senior Edificer -> Temur Battle Rage/Abrade**

Thanks again.

By the way, how did you ultimately figure out what the percentage of tutors/card draw, auras, etc. should be in this deck?

I just included all the possible relevant tutors for the deck aside from Heliod's Pilgrim because there are no ETB's in my list and Summoner's Pact because it's cmc is too high. The only tutor you should be missing is Gamble, but I wouldn't recommend including it.

I didn't really use hypergeometric distribution for anything other than ramp. A lot of my inclusions are just based upon testing alone. For example, at one point I had both Sram and Spiritdancer but later realized that I only had 19 aura's. I came to the conclusion that I didn't want two of an effect that only triggers ~20% of the time and as you can tell Sram's removal has worked out well for me.

Even with all of our hard work optimizing your list, we are just brainstorming concepts and you will still probably realize some things you don't like once you start playing the deck more.

As a side note, if you actually want to link my profile in the update put double square brackets around my name.

You're right: I'm sure I'll continue fine-tuning this deck as I go, and I've created a user link as well.
