Return Mangler and Blessed Penetrator

[Akanamah]

I will remind everyone that this is a game.
And in most games - for example HC and GWENT.
when developers are nerf. even at 0000000.1% whatever. they allow players to get full value (in this case "cards") back.
Thus, the developer insures players against losing their time / money / gold.
I think it's fair.
