Peer into the Abyss + Psychosis Crawler

Overview

When Peer into the Abyss resolves, the target player draws ceil(L/2) cards one at a time, and Psychosis Crawler will trigger once for each of those individual draws (so it triggers ceil(L/2) times) causing each opponent to lose 1 life per trigger; the target also loses half their life rounded up as part of the same resolution [Ruling 2011-06-01] [Ruling 2020-06-23]. If drawing runs into an empty library, the player will lose the game the next time a player would receive priority .

Step 1

Determine L, the number of cards in the target player’s library at the time Peer into the Abyss resolves and compute the number of cards to draw as ceil(L/2) (rounding up) per Peer’s text and its ruling [Ruling 2020-06-23].

Step 2

Perform the draws one at a time; each individual card draw is a separate draw event .

Step 3

Each time the drawing player draws a card, Psychosis Crawler’s triggered ability triggers (each draw generates one trigger) [Ruling 2011-06-01].

Step 4

Because the draws and the life-loss are effects occurring during the resolution of Peer into the Abyss, the triggered abilities created by those draws are put on the stack after Peer finishes resolving .

Step 5

After Peer has finished resolving, the Psychosis Crawler triggered abilities go on the stack and resolve in LIFO order (or as players choose to put other triggers on the stack), each causing each opponent to lose 1 life per trigger.

Step 6

As part of Peer’s resolution the target player also loses half their life rounded up as the card instructs; that loss occurs during the resolution of Peer into the Abyss [Ruling 2020-06-23].

Step 7

If during the sequence a draw is attempted when the library is empty, the attempted draw causes the draw-from-empty-library state and that player will lose the game the next time priority would be received .

Resolution

If the player drawing the cards controls Psychosis Crawler, Peer into the Abyss causes that player to draw ceil(L/2) cards (L = number of cards in that player’s library) and Psychosis Crawler triggers that many times, so each opponent loses that many life total points; the drawing player also loses half their life rounded up as Peer instructs [Ruling 2011-06-01] [Ruling 2020-06-23]. The individual draw events (and thus the Psychosis Crawler triggers) are created during Peer’s resolution and the triggered abilities are put on the stack after Peer finishes resolving . If a draw attempt happens when the library is empty, the draw causes that player to meet the “attempted to draw from an empty library” state and they lose the game the next time priority would be received .
