Moaning Wall

I know its a common but…

I was messing about getting mastery on a few cards and Moaning Wall was played by me. The creatures power is 1 and it has an X across it and the creature has the disabled effect, however the only text on it says cycling 2. It doesnt state cannot attack.

It’s a Wall. MtG Walls cannot attack by default unless specified. still, the text should state this fact since not everyone plays the paper version of the game.

other walls state this. this one does not. hence the question
