Another Mishra Q:

[Infinitium]

Recently got this on MWS: standstill player gets Mishra's Factory and Mutavault in play under standstill facing down my Mishra and Wasteland. The player tries to push through with a 3/3 Mutavault, but is rather taken aback by me wasting his Factory in response to him activating Mutavault. After fumbling back and forth for a bit he then realizes that he can activate mutavault again in response to the Wasteland trigger. Cue log.


<Simon Says> Thinking
<Peter (CAT)> ok?
<Peter (CAT)> waste is on grave
Simon Says sacrifices Wasteland
<Simon Says> pretty sure it's still a 2/2
<Peter (CAT)> ?
<Peter (CAT)> +1+1
<Peter (CAT)> is on stack =
<Simon Says> the original activity activates after mishra and sets the P/T
<Simon Says> *activation
<Peter (CAT)> another time?
<Peter (CAT)> bye noob
<System> Player Lost

In any case does the P/T setting of the Mutavault ability override the temporary boost from Mishra's Factory? It's my understanding from the Humility thread that permanent P/T setting abilities are applied by timestamp in this case?

[Nonex]

Your understanding is somehow correct (they all are just different temporary effects), but after M10 changes, layers work a little different than before. Now effects that set P/T to specific values (Mutavault becoming 2/2) always apply before effects that modifiy P/T but not to specific values (+1/+1 from Mishra's Factory), because they are now separated in different layers (7b and 7c, respectively).

Long story short, a Mutavault that would have been 2/2 before M10 is now 3/3.

Can you explain that better?

[luma]

Mutavault's ability applies in layer 7b, and the boost from Mishra's Factory applies in layer 7c. So, first both Mutavault activations make it a 2/2, then Mishra's Factory's ability gives it +1/+1, so Mutavault will be 3/3.


613.3b Layer 7b: Effects that set power and/or toughness to a specific number or value are applied.
613.3c Layer 7c: Effects that modify power and/or toughness (but don’t set power and/or toughness to a specific number or value) are applied.
