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.
