I'm not sure what you mean, could you be more specific? It's the same in that it's a non-creature permanent that you can temporarily turn into a creature using an activated ability, but it has a lot of difference from the keyrunes as well.
I'm going to guess they are asking in terms of whether it can attack the turn it comes into play: No, it will still have summoning sickness just like everything else including keyrunes.
Let's all guess the hidden meaning and answer a different version!
If you are asking if you can cypher things onto it and they stay there than yes. Also all types of counters including +1/+1 counters stay on it as well like keyrunes.
i think the answer might actually just be "yes"...
apart from the fact that it is a land, instead of being an artifact.
LOL :P thanks for not raging about me being asleep..sorry i wasn't accurate with my question
i mean keyrunes can transform and attack after a turn has passed and i put mutavault into my friends deck and i want to know after 1 turn can it transform into the monster and attack
