Mutavault Under Humility
Judge Level 2All creatures are 1/1 — except the land that activated later.
Cards involved
The land wakes up
Humility is already on the battlefield. AFTERWARDS you activate your Mutavault: "… becomes a 2/2 creature with all creature types until end of turn. It's still a land."
What happens?
Mutavault attacks.
How big is it?
Pick an answer to continue.
Humility (static, timestamp = entering) and the Mutavault effect (resolved ability, timestamp = activation) both set values in 7b — the later one wins (613.7). Layer 6 does strip Mutavault's abilities, but the animation effect isn't an ability of the permanent — it keeps applying.
613.7Within a layer or sublayer, determining which order effects are applied in is usually done using a timestamp system. An effect with an earlier timestamp is applied before an effect with a later timestamp.
613.4Within layer 7, apply effects in a series of sublayers in the order described below. Within each sublayer, apply effects in timestamp order. (See rule 613.7.) Note that dependency may alter the order in which effects are applied within a sublayer. (See rule 613.8.)
The result
A 2/2 creature land with all creature types (types are layer 4 — Humility changes nothing there), but without abilities. It hits for 2.
613.7Within a layer or sublayer, determining which order effects are applied in is usually done using a timestamp system. An effect with an earlier timestamp is applied before an effect with a later timestamp.
The other way around
If Humility enters AFTER the activation, it holds the later timestamp — then the attacking Mutavault is just a 1/1. Same principle as the Humility/Opalescence endboss: 7b belongs to the later clock.
