Milling sounds attractive because you get to "destroy" many of your opponents cards at once

There are a couple of cards Shark Typhoon and Shark token that grabbed my attention and imagination from Ikoria

And this doesn't even include the free dig spell Once Upon a Time, the endless Zombies from Field of the Dead, or the annoying loops generated by Mystic Sanctuary

It still has annihilator four, but the key thing here is the difference in the ability that triggers when you cast them

The card underwhelms me in the stock precon, but for aggressive, mono-white lists whose options for card draw are limited, it seems like a welcome addition
