Thanks for the primer, very useful. I’m not sure if this works but maybe Matter Reshaper if it does work then you get two cards from the top. If it doesn’t work please let me know. Thanks for everything!

match_lighter Reshaper definitely works with Teysa. You'll get some mix of drawing cards or playing low cost permanents. These permanents could also be lands which is good ramp. I'd say this is probably the best card draw you'll get from a self death trigger, much better than Filigree Familiar or the like. Added to the maybeboard and thanks for the suggestion.

Thanks Masterful for the earlier explanations, I have come to agree with them.

What do you think of adding Ranger of Eos since you now have 2 creature sac outlets and Hangarback Walker, and also mainboarding Recruiter of the Guard

ThaneGarrus Those are actually really good ideas. That package seems incredibly useful since ranger or recruiter can provide up to 3+ creatures for sacrifice fodder each, or they could fetch outlets. Hangarback was also something I've been considering for some time, and I think ranger would really push it into mainboard territory.

The problem is what to cut. I'm considering Deathrender since it might be a bit too narrow, Carrion Feeder since ranger would act as a second Viscera Seer anyways, Martial Coup or Living Death because we already have many ways to deal with creatures, and Teysa, Orzhov Scion as her abilities are quite restricted. I love the idea that I can recruiter for ranger, ranger for seer and doomed traveler, sac doomed traveler to get two tokens with Teysa, then sac all of them to get a billion death triggers. Also the fact that recruiter can tutor for card draw, ramp, sac outlets, and tokens makes him very hard to pass up.

I agree on Deathrender , Martial Coup and Living Death , but I like having a backup fetch in Carrion Feeder if viscera seer gets exiled or we don’t have a way to recur it. Teysa, Orzhov Scion is pretty restrictive to use outside of the combo with Darkest Hour

I was toying with the idea of Stoneforge Mystic , Sword of Light and Shadow (recursion/protection), Nim Deathmantle (combo potential) and Open the Armory since skullclamp is such a powerhouse Possibly cutting Mentor of the Meek
