I didn't know that but I think it was the guy who also kept saying necrovalley would be added, which was true. I just saw a dude last box release saying save up because goyo guardian is coming.
Trust me, I wished goyo guardian would come out around one year ago and I remember someone telling the same sentence that time. I think he is also the one who predicted wrongly that we would have gotten brd and blackwing when they actually came much later. He basically keeps saying that after every box until he's lucky.
At least he is still better than the autistic conspiracy guy who said tiered to every single archetype in this game just to manipulate people to waste their gems
