Interesting list, I've been curious to build a Numot deck but unsure of where I was going to take it. You have some good stuff in here, seeing a little bit of a tax sub theme running through your list, paired with LD seems relevant. How has the deck been working for you?
I like the War's Toll in a deck like this, forcing your opponents to use all of what resource they have left after you've triggered Numot would limit the responses and survival tricks by said opponents. Grand Abolisher could limit the inevitable Cyclonic Rift on attacks as well.
