Kaervek, the Spiteful + Maha, Its Feathers Night

Overview

Maha, Its Feathers Night sets creatures your opponents control to have base toughness 1 (Ruling [2024-07-26]). Kaervev, the Spiteful’s continuous static ability gives “other creatures” -1/-1, which modifies those creatures’ toughness. Applying Maha’s base-toughness-setting effect and then Kaervev’s -1/-1 modifier can reduce an affected creature’s final toughness to 0, in which case it is put into its owner’s graveyard by a state-based action . If damage is already marked on a creature, lowering its toughness can make that marked damage lethal (damage remains marked until cleanup) and cause destruction via state-based actions and ; see also Ruling [2020-06-23].

Step 1

Identify which creatures are affected by Maha’s ability: Maha makes creatures your opponents control have base toughness 1 (Ruling [2024-07-26]).

Step 2

Apply effects that set a creature’s base toughness (Maha’s effect is a base-toughness-setting continuous effect in this context; it overwrites earlier base-toughness-setting effects and is overwritten by later ones per Ruling [2024-07-26]).

Step 3

Apply continuous modifiers that change power/toughness (Kaervev’s “Other creatures get -1/-1” is a static modifier that adjusts power and toughness).

Step 4

Calculate each affected creature’s final toughness after applying base-setting effects and modifiers; if the final toughness is 0 or less, put that creature into its owner’s graveyard as a state-based action .

Step 5

If a creature has damage already marked on it, compare that marked damage to the final toughness; if the marked damage is greater than or equal to the final toughness, the creature is destroyed by state-based action for having been dealt lethal damage and .

Step 6

Remember that damage marked on creatures remains until cleanup , so changing a creature’s toughness during the turn (for example by Kaervek entering) can change whether existing marked damage becomes lethal (Ruling [2020-06-23]).

Resolution

If Maha’s ability is making a creature’s base toughness 1 and Kaervek’s -1/-1 applies to that same creature, the creature’s final toughness becomes 0 and it’s put into its owner’s graveyard as a state-based action . If the creature already has damage marked on it, lowering its toughness can cause marked damage to be >= toughness and be destroyed by state-based actions and (damage remains marked until cleanup ) — Kaervek entering or leaving can therefore change whether a creature dies this turn (Ruling [2020-06-23]). Maha’s toughness-setting ability will overwrite earlier effects that set base toughness and be overwritten by later ones (Ruling [2024-07-26]).
