Bloodletter of Aclazotz + Unstoppable Slasher

Overview

On your turn, when Unstoppable Slasher deals combat damage to an opponent, two separate life-loss events occur: the life loss that results from the damage and the separate life-loss event created by Slasher’s triggered ability. Bloodletter of Aclazotz’s replacement effect doubles each life-loss event that an opponent would suffer during your turn, but it does not change the amount of damage actually dealt or any life gained from that damage [Ruling 2023-11-10].

Step 1

Unstoppable Slasher deals combat damage to an opponent during your turn; process the damage event (apply damage replacement/prevention to the damage itself) .

Step 2

Because damage was dealt, Slasher’s triggered ability 'Whenever this creature deals combat damage to a player...' triggers and is put on the stack waiting to resolve .

Step 3

Resolve the damage event into results: the opponent loses life equal to the damage dealt (this is the damage → life-loss conversion) .

Step 4

Bloodletter of Aclazotz’s replacement effect applies to that life-loss event (it’s an opponent losing life during your turn) and replaces it with 'they lose twice that much life instead' so the opponent loses twice the damage amount instead of the damage amount .

Step 5

Later, when Slasher’s triggered ability resolves, it creates a new life-loss event instructing the opponent to 'lose half their life, rounded up.' That is a separate life-loss event from the damage-turned-life-loss event .

Step 6

Bloodletter’s replacement effect also applies to this triggered life-loss event and replaces it with 'lose twice that much life instead,' so the opponent loses twice the computed half (rounded up) .

Step 7

Apply the two doubled life-loss events to the opponent’s life total; Bloodletter did not change the damage dealt and did not change any life gained tied to the original damage event (see Ruling) [Ruling 2023-11-10].

Resolution

If Unstoppable Slasher deals combat damage to an opponent on your turn, do the following: the damage is dealt (damage-triggered abilities trigger) ; the damage is then processed into results and becomes life loss equal to the damage dealt (that life loss is doubled by Bloodletter as a replacement effect) ; later, Slasher’s triggered ability (which triggered at damage) resolves and instructs the opponent to lose half their life rounded up — that life-loss event is also replaced by Bloodletter to be twice that amount . Bloodletter never changes the amount of damage dealt nor life gained from damage (see Ruling) [Ruling 2023-11-10].
