Yoooo, this is my work-in-progress Mayael the Anima EDH deck! I've been building it for around 2 months now and have only been playing EDH itself for about a year. That leaves plenty of room for improvement and so I'm posting my current list in hopes that some of the more veteran players out there can help point me in the right direction. This deck has proven itself to be more than capable of dealing with some pretty intense opponents but I feel like it could be so much more consistent and smooth than it currently is. Feel free to ask any questions and point out any obvious omissions that I need to include in the deck!
Here is what i personally would cut: Akroma, Angel of Wrath- She's just a big dumb creature, which is cool, but I prefer my EDH creatures to do more. Thundermaw Hellkite - See above Borborygmos Enraged - I played him in my list for a long time, he always under preformed. I never have lands in hand, even when i added every bounceland in my colors. Spellbreaker Behemoth - When Mayael gets going, you don't need to cast spells. Stalking Vengeance - I don't think you need to burn the opponent. Xenagos, God of Revels - I just wasn't ever happy when i played him.
That's the Mayael targets i don't like. I would replace them with: Utvara Hellkite - He can win the game on his own. Scourge of the Throne - Its Aurelia #2, but works with Utvara Hellkite! Inferno Titan - Mayael decks are notorious for not having much removal, but this guy can remove a lot of the utility creatures in the format. Scourge of Kher Ridges - More removal that is also a Mayael target, and works with Utvara Hellkite. Thunderfoot Baloth - Just a better Xenagos, God of Revels if you ask me. Eternal Dragon - I LOVE Mayael targets that don't just sit in your hand when drawn. This guy is mana fixing if drawn. Plus, its a dragon.
Now i would like to recomend changing up your Lands. Here is what i would cut: Tree of Tales, Great Furnace, Ancient Den - I'm not sure why you have the artifact lands, they die to mass artifact removal or turns Naturalize into LD. Razorverge Thicket, Copperline Gorge - Fastlands generally aren't good in EDH, in a 99 card deck it's hard to draw them before turn 4. Battlefield Forge, Karplusan Forest, Brushland - I'm not a big fan of painlands in EDH either.
I would add: Gruul Turf, Selesnya Sanctuary, Boros Garrison, Karoo, Dormant Volcano, Jungle Basin - Bouncelands are awesome. Synergy with Garruk, Voyaging Satyr, Magus of the Candelabra, Krosan Restorer, Weathered Wayfarer, etc. Kessig Wolf Run - Can win you the game when you have stuff like Vorinclex, Voice of Hunger. Jungle Shrine - Taps for all 3 colors.
Now to the ramp: Arbor Elf - I feel like sometimes he wouldn't even tap for mana if you get screwed off forests. Avacyn's Pilgrim - 1 mana 1/1 that taps for only one isn't where you wanna be in EDH. Sakura Tribe Elder - He is fine usually, but i think you can do better. Druid of the Anima - She is just too vanilla for my taste. Farhaven Elf - He is also usually fine, but i think you can do better. Khalni Heart Expedition - Just not a big fan of this one. Darksteel Ingot - I think you can do better. Chromatic Lantern - See above.
I would recommend adding: Sylvan Scrying - It may not go on the field but when you can get a Maze of Ith or Kessig Wolf Run it's worth it. Weathered Wayfarer - See above. Magus of the Candelabra, Krosan Restorer, Voyaging Satyr - Goes well with the bouncelands if you decide to go that route. They also go nicely with Maze of Ith and High Market etc. Bloom Tender - Turn 2 him, turn 3 Mayael, turn 4 activate Mayael. Exploration - Turn 1 exploration, turn 2 Mayael, turn 3 activate Mayael. Harrow - Just an all around good card in EDH.
Tutor and Draw: Harmonize - Usually i like Harmonize but here i think it can be replaced. Green Sun's Zenith - I don't like the restriction of only getting green creatures.
I would add: Eladamri's Call - A better GSZ in my opinion. Greater Good - I take the fact that you're running High Market as you know the power of a sac outlet. Here is one that draws cards!
Miscellaneous: Mimic Vat - I don't think it reaches it's full potential in this deck.
Adding: Swiftfoot Boots - Just another way to protect Mayael.
So those are my suggestions! Sorry if they sounded mean lol hope they were helpful. I tried keeping them budget friendly since i wasn't sure what your opinion was on that (though you are running eldrazi titans...) and i tried trading ramp for ramp, creatures for creatures etc. If you want more help definitely check out the primer on Mayael here on the site, it helped me alot when i was building my Mayael deck.
