So I think they changed the how the Aldor but not Edwin. I know for sure when the expac went live if you Aldored a Tar Creeper it went down to 1 attack. I know because I did it and also Trump did it on Stream and even said it shouldn't work. But it seems after the patch yesterday it no longer works. I was unsure of the Edwin (I know how he works now, he gets the buff) I thought I read that he would always be a 5/5 and maybe he changed along with the Aldor change.

So I've just been researching and it appears the Aldor thing was a bug and was fixed a while ago
