Sorry to bother you about this then- I do appreciate that you were able to (mostly) clear up our confusion though.
I checked 'in game' as with your screenshot and it does say "All enemy Monsters have" -1 Armor/Health for the debuffs. So, it looks like- as far as anyone knows: the opposing team all gets -1 Armor/Health not your team.
Whether that holds when the card is released is, of course, anyone's guess.
It's fine, just don't want people misunderstanding the situation. I can't speak for them in any official capacity.
As far as the card, I suppose they could change it, but since they published the post and then loaded it onto the site today, my guess is this is it.
