Zell seems like an interesting addition to land-focused decks in both Standard and Commander
Whats even more amazing is how efficient every part of the card ends up being, to the point that the biggest weakness on Shigeki is a lack of haste
At worst, this is a 5 mana, draw multiple cards spell, essentially, assuming you immediately kill it for its -3 ability
Modern and Legacy will take some time to rebound and regroup from the Grief ban, but the card advantage of Necrodominance seems extremely powerful in a shell which can use those draws to grind away opposing hands for minimal mana cost
Past that, if you play the 93/94 format, there are few other creatures better in black
Because this is owner, and not controller, that means you can kill people off if you roll a 20 and can kill off the chosen Creature
