Nvm I figured it out

And also does anyone know exact date of rotation?

Guys can someone please answer me if I see it correctly;

OP says if you already own copy of non-golden card that is going to hall of fame, don’t craft golden cause you won’t get any bonusdust;

But if I own for example non-golden Genn Greymane and disenchant him, craft golden one and then getting HOF refund and disenchant him the math should be like this: +400 – 3200 +3200 + 1600 = 2000 whereas if I don’t own golden legendary and just craft and de+refund I earn 1600
