cool deck!!!
i found Seal of Removal pretty useful in my muldrotha deck.
also i run Mindslaver as a wincon.

Thanks, Grind! I see the value in Mindslaver, but would rather win differently. I'd thought about a lands theme, but have decided against it for now, too.

My main suggestion is to clean up your custom categories. Would make it easier to read and understand. You can throw Uro 's lonely section away entirely, consolidate your sac outlet categories, cut your utility category altogether, and throw your boardwipes into removal. But that's just aesthetic shit, super up to you.

As for cards themselves... you could use some land upgrades. Shocks , Fetches if you can afford them, etc.

Given you're not a landfall strategy, Tatyova, Benthic Druid ought to go. Stroke of Genius can replace it.

Good luck with your deck!

Omniscience_is_life, thanks for the suggestions. Even though I'm not using a landfall strategy, Tatyova is still so good! She'll be hard to cut, but I'll consider it. I can't afford the more expensive lands, so the mana base has to stay where it is for now.

I hadn't realized I had two sac outlet categories. I've fixed that, and combined the boardwipes into removal. Others I've left for now. I'll see if I can clean more up as I go.

How do you feel about Destiny Spinner ? I feel like it would help protect some of your big plays. I think Sphinx of the Second Sun might be cool in here too if you think you could fit it. Another draw and untap is useful, plus you'd trigger your sagas twice a turn. The only downside I can see are cumulative upkeep cards like Elephant Grass and Mystic Remora .

I'd replace Mental Discipline with Compulsion . Compulsion is a straight upgrade in that it costs less and it can sac itself for a card too.

Getting into more expensive stuff, I feel like Squandered Resources would allow for some absolute bomb plays in here. City of Solitude and the much more affordable Dosan the Falling Leaf would protect you quite well, considering you only run two instants I don't think they would hold you back much at all.

As far as cuts go, I would look at Ob Nixilis, the Hate-Twisted , Davriel, Rogue Shadowmage , and Arlinn, Voice of the Pack look/feel weak to me. I don't think they offer much to the deck and while Arlinn does make tokens it feels kind of meh compared to other walkers like Vraska.

Medomai's Prophecy seems pretty weak to me as well, maybe you have different experiences than I do but it feels really weak compared to other sagas. Having to name your next play could be risky too depending on what you have for options in your hand.

+1 from me, really cool take on Muldrotha!

Lhurgyof, thank you for those suggestions! I only have Squandered Resources and Destiny Spinner on hand right now, but on the next order, I'll probably pick up a few more of your suggestions! I'll definitely make the switch for Compulsion .
