Traumatize + Fraying Sanity

Traumatize

Fraying Sanity

How it works

1. Cast Traumatize by paying 3, causing the opponent enchanted by Fraying Sanity to mill cards equal to half their library size, rounded down.
2. At the beginning of your end step, Fraying Sanity triggers, causing the opponent to mill cards equal to the number of cards put into their graveyard this turn.
