jsnrice, It sounds like you just want this to be a completely different deck than what it's explicitly intended to be, lol. 

As I've outlined multiple times, this deck is purposefully built to be more of a grindy, mid-game deck. I would definitely consider turn 5 to be mid-game if not late early-game for a majority of casual EDH games; so it sounds like it's actually operating at the intended pace. 

Additionally, if you look at the actual mana curve stats of this deck, 80-90% of the cards in this deck are playable on turn 4 or earlier; and a majority of the cards in this deck cost either 2 or 3 mana. You're simply incorrect about this deck's mana curve and that's not even in consideration of the fact that this deck is intentionally aiming to reanimate the more expensive enchantments for free. Your issues with the pacing of the deck sounds like you either just want to play a different more competitive, faster-paced deck, or are  having personal difficulties with mulligans/starting hands and early game play sequencing. Realistically 5 playtests is wayy too small of a sample size to make any definitive claims, especially in a format with such high variance; and sometimes the rng gods just give you slower starts. 

I appreciate your recommendation to track gameplay stats, I already do so actually, and have playtested this deck specifically an absurd number of times. I've literally gone through about 4 complete overhauls of this deck as a result of all of my playtesting. Again, this decklist is focused on a few very specific restrictions in order to achieve a specific gameplay experience/play at a specific pace; which your suggestions don't reflect. I understand that fast mana leads to having access to more mana faster, lol; that just isn't the play experience that I'm trying to curate with this build.

jsnrice, I'm wondering if maybe I worded the questions I asked poorly, since they weren't addressed. I'd love to hear more about your playtesting experience, as well as what criteria you're operating under to determine if a deck is performing too slowly!

As for your most recent card suggestions, I feel like they're missing the goals of this deck; have you read the primer? First and foremost this is an enchantment deck, so I'm prioritizing enchantments for my packages as much as possible. Secondly, I'm purposefully aiming for more of a grindy, mid-range build to focus on taking advantage of Anikthea's abilities. Slotting in two pieces of off-theme, artifact-based fast mana would not be appropriate for any of my goals for this deck.

As for your cut suggestions, Im a bit confused because at the very least Smothering Tithe is incredibly worth it in this deck; even in a faster/higher-powered meta. It's an enchantment, it makes tokens which this deck is already aiming to abuse, and it can both simultaneously slow down opponents who respect the absurd ramp potential of Smothering Tithe, while also helping my deck accelerate to a game-winning boardstate. I could totally understand arguments to cut Mirari's Wake and/or Shigeki, Jukai Visionary to slot in faster ramp options; if you're playing in a higher-powered meta. But even then I'd personally probably prefer more on-theme options such as Carpet of Flowers, Utopia Sprawl, or Fertile Ground. 

Finally, sincerely, thank you again for taking the time to comb over my decklist, offer your insight, and even playtest the deck. I truly appreciate it, even if we don't agree on card choices (which leads to one of the more fun aspects of this game; deck diversity)!

jsnrice, hi again, thank you for taking the time to playtest the deck!

I would love a bit more information, if possible.

Specifically, when you say that the deck feels too slow, what would be your criteria for 'fast enough'; what's leading you to that conclusion?

Additionally, do you have any playtest stats? How many games did you play before deciding there is too much removal and not enough ramp? Was this a handful of solo goldfish games, or multiplayer pods?
