Commander - Aminatou, the Fateshifter

I want to continue the Commander deck improvements (that I started with Saheeli) with Aminatou, the Fateshifter. Here's the base deck:

Instant Aethermage's Touch Utter End Banishing Stroke Return to Dust Brainstorm Predict Telling Time Esper Charm Mortify Crib Swap	Artifacts Azorius Signet Commander's Sphere Crystal Ball Dimir Signet Mind Stone Orzhov Signet Seer's Lantern Sol Ring
Enchantment Lightform Cloudform Primordial Mist	Sorcery Terminus Aminatou's Augury Entreat the Dead Skull Storm Entreat the Angels Army of the Damned Akroma's Vengeance Devastation Tide  Dream Cache Ponder Portent  Treasure Hunt
Lands Isolated Watchtower 8 Plains 5 Island 3 Swamp Forge of Heroes Arcane Sanctum Azorius Chancery Azorius Guildgate Barren Moor Command Tower Dimir Aqueduct Dimir Guildgate Dismal Backwater Forsaken Sanctuary Halimar Depths Jwar Isle Refuge Lonely Sandbar Meandering River Mortuary Mire New Benalia Orzhov Basilica Orzhov Guildgate Scoured Barrens Secluded Steppe Sejiri Refuge Submerged Boneyard Tranquil Cove	Creatures Enigma Sphinx  Varina, Lich Queen Yennett, Cryptic Sovereign Boreas Charger Magus of the Balance Night Incarnate Sower of Discord Yuriko, the Tiger's Shadow Serra Avatar Adarkar Valkyrie Conundrum Sphinx Djinn of Wishes Jeskai Infiltrator Sphinx of Jwar Isle Sphinx of Uthuun Phyrexian Delver Duskmantle Seer High Priest of Penance Silent-Blade Oni Loyal Unicorn Loyal Subordinate Geode Golem Mulldrifter  Ninja of the Deep Hours Sigiled Starfish Pilgrim's Eye

 
OK, so this deck..................

I hate it.

Aminatou doesn't do anything really interesting, the ultimate is the sort of play that makes games go on FOREVER, and the setup/payoff for that ultimate is way too much work, the mana base is absurd with all the lands that enter tapped, I actively despise Lightform and Cloudform, Aethermage's Touch is not a thing, stop trying to make it a thing, I am 100% sick of WotC shoving Serra Avatar into white decks...basically, this deck exhausts me. It is for someone. But not for me.

I'm going to change it up and run Yennett, Cryptic Sovereign as my commander instead. That's the payoff card, meant to work with Aminatou, in my opinion. I'd much rather encourage game states where I am pushing things towards the conclusion, even if that conclusion is: I lose.

So here we go.
