I’m don’t think the polar bird would work out too well for pulling double duty as a ground blind considering it doesn’t have windows. Unless they made some design changes since last year I would pass on the polar bird. I’ve heard great things about them considering ice fishing though.
However, you should shop around. I bought my Shappell WideHouse 5500 about 5-6 seasons ago (for under $200) and I can set it up and take it down literally in just a few minutes by myself. It’s a super easy setup. I’ve never broken a pole, window, zipper, or had any of the fabric tear or fray. The ice anchors aren’t that bad either. I usually put one through a rivet in the skirting opposite of the wind and I’ll use another with the tie-down strap on the hub facing the wind, all by hand. I’ve never had any of the hubs collapse on me either.
Overall, it’s been a real nice hub shelter that has worked out well for me the past 5 seasons. I wouldn’t hesitate to use it as a ground blind either other than it’s blue and not camouflage but in my experience, that doesn’t matter all that much if at all. Set it up a week before the season starts so it isn’t a new thing in the woods and you’re good to go.
