It looks a lot like the build I play combined with the oddities Saito had in his 4th place finish in GP Madrid.
( + preordain instead of mystical and 2 tendrils + the crystal vein)

The strength of the new Ad nauseam list is the protection from wasteland, but I really doubt the second tendrils and the crystal veins.
Sideboard also looks like Saito's GP Madrid.

yet, he has a good run online
