My friend, let me introduce you to Afterlife Insurance... I have a feeling you two will get along nicely! (note: it doesn't say non-token)

Will you be adding Ocelot Pride? Think it's worth replacing for any on the one drop afterlife creatures? Trying to find a home for it in my own build and think I may pull Garrison Cat for it. Marionette Apprentice Seems like another great addition but having an even harder time finding room for that one.

Saw this in another deck but Athreos, God of Passage might be kinda fun here too. Feels like it would synergize nicely.

Looks good. To upgrade your mana base, I'd get a Marsh Flats and Urborg, Tomb of Yawgmoth. If you can afford a Scrubland, you can afford those. Also for sac outlets, I'd replace Spawning Pit *list* with Woe Strider.

You should cut Myr Sire, Martyr of Dusk, Carrier Thrall and replaced them by Indebted Spirit, Infestation Sage, Wriggling Grub.

Personnally i would also replace Priest of Forgotten Gods by Viscera Seer, i find the sacrifice 2 creature + tapping too restrictive.

Do you often play Anointed Procession, Drivnod, Carnage Dominus, Mondrak, Glory Dominus ? I must admit i don't play them although I would like because they don't do anything when they arrive.
