Fraying Sanity + Terisian Mindbreaker

Overview

When Terisian Mindbreaker attacks it mills half of the defending player's library (rounded up). Fraying Sanity then counts all cards that were put into that player's graveyard during the turn (including the cards milled by Mindbreaker) and, at the beginning of the next end step, its triggered ability will cause that player to mill that many additional cards; Unearth returns and exiles Terisian at the beginning of the next end step per its ability , and Fraying Sanity’s count behavior is governed by the rulings on its trigger [Ruling 2017-07-14].

Step 1

Terisian Mindbreaker attacks; its triggered ability “Whenever this creature attacks, defending player mills half their library, rounded up” goes on the stack and resolves during the combat sequence (the defending player puts that many cards from the top of their library into their graveyard).

Step 2

All cards put into the defending player's graveyard this turn (including the cards milled by Mindbreaker) are counted for Fraying Sanity’s later trigger; Fraying Sanity’s ability will determine the number of cards to mill when that ability is applied, and that determination is based on the number of cards put into the graveyard during the turn up to resolution time and the published ruling about Fraying Sanity’s counting behavior [Ruling 2017-07-14].

Step 3

At the beginning of the next end step Fraying Sanity’s triggered ability triggers if Fraying Sanity is on the battlefield at that moment; the Unearth delayed-exile trigger (if Terisian was unearthed) also triggers at that time per Unearth’s text .

Step 4

Triggered abilities for the beginning of the end step are placed on the stack in APNAP order; whichever trigger resolves first will do its action first, but Fraying Sanity’s mill will use the count of cards put into the graveyard earlier that turn when it resolves .

Step 5

When Fraying Sanity’s ability resolves it mills X cards equal to the number of cards that were put into the enchanted player's graveyard that turn (if fewer than X cards remain in the library, the player mills all remaining cards). Milling into an empty library does not itself cause a player to lose the game — only attempting to draw from an empty library causes a loss per state-based actions .

Resolution

Result: Terisian Mindbreaker’s attack-trigger mills half of the defending player’s library immediately. Fraying Sanity’s beginning-of-end-step triggered ability will count those cards and will cause that player to mill that many cards at the beginning of the end step (even if Fraying Sanity wasn’t on the battlefield when the milling happened) [Ruling 2017-07-14]. If Terisian was returned by Unearth, it will be exiled at the beginning of the next end step according to Unearth’s text , but its attack-trigger already resolved earlier in the turn.
