This is another highly specific card that will only see play in Dimir Zombies archetype in commander and maybe standard.
It has a fantastic effect but since it's limited to zombies tribe, it will not be able to turn into an investment darling anytime soon. For all its worth, expect it to fall to $8-12 a piece.
If it finds home in some unexpected standard brew, then it may go above that but not by much. It's just too niche to make any difference in any format whatsoever.
