Bloodletter of Aclazotz + Peer into the Abyss

Overview

On your turn, Bloodletter of Aclazotz’s replacement effect doubles any life loss an opponent would suffer, so when you cast Peer into the Abyss targeting an opponent that opponent draws ceil(library/2) cards and then loses twice ceil(life/2) life; the life-loss amount is determined by Peer (rounded up) and then doubled by Bloodletter, and the life total is adjusted accordingly . Rulings clarify that Bloodletter doubles life loss but does not change damage amounts or lifelink gains [Ruling 2023-11-10] and that Peer’s “round up” applies to the amount lost, not to remaining life [Ruling 2020-06-23].

Step 1

When Peer into the Abyss resolves, compute the two values separately: cards to draw = ceil(number of cards in target’s library / 2) and life to lose = ceil(target’s current life total / 2) [Ruling 2020-06-23].

Step 2

Apply the draw: the target draws the computed number of cards (this draw is not affected by Bloodletter) [Ruling 2020-06-23].

Step 3

Apply replacement effects that modify life loss during your turn: Bloodletter of Aclazotz replaces the life-loss event with ‘lose twice that much life’ because it’s your turn, so the life to lose becomes 2 × ceil(their life / 2) [Ruling 2023-11-10].

Step 4

Adjust the target’s life total by subtracting the doubled life-loss amount; perform the life-total change as described by the rules for life adjustments .

Step 5

If the life-total change reduces the player’s life to 0 or less, that player loses the game (standard game loss conditions follow after state-based actions).

Resolution

If you control Bloodletter of Aclazotz and it is your turn, casting Peer into the Abyss targeting an opponent causes that opponent to draw ceil(#cards in library / 2) cards and to lose 2 × ceil(their life / 2) life; the life loss is then applied to their life total (possibly reducing it to 0 or below) . The draw amount is not doubled. Bloodletter does not change any damage amounts or lifelink results (it only modifies life-loss events) [Ruling 2023-11-10], and the half-life value is rounded up before doubling as described by Peer into the Abyss [Ruling 2020-06-23].
