No reroll on Magatha

I didn’t get the option to reroll Magatha since I already own the diamond version. Anyone else have this issue?

How did you end up with two Magatha?

I first bought the golden then mini-set then non-golden later on

I think it’s possible that you bought them in the wrong order. Rerolls only occur when you already have a craftable version of the same card of lower quality.

Rerolls only occur if you gain an uncraftable card of higher quality. You gained the golden and diamond version of that card at the same time, not the golden card first and then the diamond.

The standard version of that card does not trigger a reroll because the golden version can be crafted.

I guess I gotta buy the non-golden first.

Last mini-set, I was able to reroll the golden Thaddius.
