I’m looking for some kind of easy mobile blind.

That blind a built was simi-mobile, I designed it so it could break down easy with wood screws and fit in my truck, I broke it down and moved it 4 times.

If you are wanting something real easy set up/break down each hunt, layout blind is your best bet or natural cover and dead or cut limbs/brush. I hunt public 100% of the time, and normally can always find natural cover and maybe add to it a little. The key I have found is to have cover for your face, and I don't mean face paint or mask, but being able to hide your face behind brush. This can be accomplished with a stick in the ground, and vegetation on top, like pic below. I put my face between me and the ducks and they don't see me. If ducks fly over head, I don't need a roof, put my face down and lean into the brush, they don't see me.
