Lord Xander, the Collector + Fraying Sanity

Lord Xander, the Collector

Fraying Sanity

How it works

1. Declare Lord Xander as an attacker, attacking the opponent enchanted by Fraying Sanity.
2. Lord Xander's second ability triggers, causing the opponent to mill cards equal to half their library size, rounded down.
3. At the beginning of your end step, Fraying Sanity triggers, causing the opponent enchanted by Fraying Sanity to mill cards equal to the number of cards put into their graveyard this turn.
