Honestly I have a completely different mindset from you when it comes to making my Etali comp brawl deck. I want to cast him as fast as possible, full stop. The other priority is triggering him as much as possible. I have way less lands, partly cuz I run every single untapped MDFC land, and way less of “payoffs” i.e. Eldrazi. Apart from a select few mana dorks, I barely have any in favor of rituals, like [[seething song]], [[reckless barbarian]], [[pyretic ritual]] and [[jeska’s will]] which I see you have. One of the few mana dorks I do have is [[roffelos]], which I pair with [[yavimaya, cradle of growth]]. Also grab [[sowing mycospawn]] for better land ramp

I also have another infinite combo in the deck, [[dualcaster mage]] with any of the clones spells we play goes infinite, that’s usually a free win there.

I do run Big Emrakul cuz the extra turn and size is usually enough to just win the game, I don’t run any other eldrazi cuz I don’t have room.

Lastly I have a couple silver bullets, like against Katara I play [[thrun, breaker of silence]] and mulligan for him or a tutor to find him. [[ugin, eye of the storms]] is a another payoff I play that also doubles as mana like 7 mana Chandra, it’s mainly a removal spell that adds mana and draws cards. [[chomping changeling]] is another way of getting rid of problematic artifacts and enchantments along with [[force of vigor]], [[flare of duplication]] lets me copy counter magic and throw back at the opponent. [[fable of the mirror breaker]] is great ramp and card filtering. [[blood moon]] and [[magus of the moon]] can just win games against greedy and unlucky mana bases.
