Emrakul's Sway

At the beginning of your upkeep, put an insanity
counter on Emrakul's Sway, then each player
mills cards equal to the number of insanity
counters on it.
Delirium — Whenever one or more creature
cards are put into your graveyard from anywhere,
if there are four or more card types among cards
in your graveyard, create a 3/2 colorless Eldrazi
Horror creature token.
