I think it's profitable. Though you'd better to invest to the nerfed amazoness or better vampires.
Vampires deck is very consistent for months. The future nerf i think would still make vampires playable, unless they really 🔥 the deck which is unlikely
I bought two of the boxes, and I've had some mileage out of it. The real test will be KC cup though, people will have had time to prepare by then and expect BEWD. Especially given how bricky it can be.
The trick up the sleeve ability variant also lessens up the bricking a bit by making any clogged up level 8 Dragon hand at least guarantee a 1 card 3100 beater on the field at least.
