Death-Nought

[Mr. Safety]

I'm posting my experimental Death's Shadow/Phyrexian Dreadnought list to see if I can get some good feedback. I fell on my face playing mono-blue Dreadstill recently and I wanted to see what I could do with a splash color. I don't have Underground Seas so the only viable option, if it shows itself to be viable, is playing Watery Grave + Death's Shadow. In theory it seems spicy and pretty good to me, but in practice it could be a train wreck. I like that it gives access to Thoughtseize as another way to protect Dreadnought (from annoying cards like Abrupt Decay.) I leaned pretty hard on the Ub DS template that has been established for that deck, shaving some of the pieces down to fit in the Stifles.

Here is the current list as of 11/19/19:
