I can’t give you any info on the Ameristep, but I can give you some help on the ground hunting. The positive things about the blinds are ease of setup,safer, and you can move more without being detected.
The negative side is your visibility is limited and the blind can be spotted easier than a treestand.
So with that being said, effective blind use calls for you to “blend” the blind in. It can be as simple as putting it near a bunch of grass, haybales, blowdowns, anything to break up the outline. Also, take a few branches and put them on the top and on the sides of the blind. This can all be done quickly and quietly at the time of the hunt. I like hunting out of the blind. It allows me to relax and move more which keeps me out in the feild longer.
