Kefka, Court Mage // Kefka, Ruler of Ruin + Psychosis Crawler

Overview
When Kefka, Court Mage’s enter-or-attack ability resolves you make each player discard, then you draw N cards (N = number of card types among those discarded). Psychosis Crawler triggers once for each card you draw, so those N draws cause N Psychosis Crawler triggers (Ruling [2011-06-01]). Each of those triggers will, when they resolve, cause each opponent to lose 1 life; if Kefka is already transformed into Kefka, Ruler of Ruin that life loss during your turn will trigger Kefka to draw more cards, which in turn creates additional Psychosis Crawler triggers and can loop until a player loses the game under state-based actions . The draw sequence and replacement interaction follow the draw rules and .
Step 1
Kefka's triggered ability (enter or attack) begins to resolve and causes each player to discard a card, then instructs you to draw a card for each card type among cards discarded this way.
Step 2
All discards from that ability happen as part of the ability’s resolution (they’re one event), then the ability determines N = the number of card types among the discarded cards and you begin to draw N cards as the next part of that same resolution; drawing multiple cards is treated as a sequence of individual card draws governed by and .
Step 3
Each time you draw a card, Psychosis Crawler’s triggered ability triggers. Because you drew N cards, Psychosis Crawler creates N separate triggered abilities on the stack (Ruling [2011-06-01]).
Step 4
Those Psychosis Crawler triggers are put on the stack and will resolve in the normal manner. Each time one resolves, each opponent loses 1 life (this is the effect of the resolved trigger).
Step 5
If Kefka is currently Ruler of Ruin (the transformed side) when any of those life-loss events happen during your turn, Kefka’s triggered ability sees that life loss and will trigger to draw that many cards for you; those draws are events that in turn create additional Psychosis Crawler triggers, which go on the stack and resolve, producing further life loss and further Kefka draws, and so on.
Step 6
This cycle continues resolving triggers normally until it stops changing the game state or until a player’s life total is 0 or less and they lose the game per state-based actions .
Resolution
If Kefka, Court Mage (front side) causes you to draw multiple cards, Psychosis Crawler will trigger once per card drawn (Ruling [2011-06-01]). If Kefka is still the Court Mage (not transformed), those triggers simply make each opponent lose life equal to the number of cards you drew. If Kefka is already Kefka, Ruler of Ruin (transformed) before the life loss happens, each instance of life loss during your turn triggers Kefka, Ruler of Ruin to draw that many cards, which in turn produces more Psychosis Crawler triggers and can repeat; the loop continues resolving normally and will end when a player’s life total is 0 or less and that player loses the game via state-based actions . Drawing and replacement effects follow and . The {8} activated ability that makes each opponent sacrifice a permanent resolves with the choice order and sacrifice simultaneous procedure described in Ruling [2025-06-06].
