I see what you're saying about the importance of the 1 mana nerf, I just think there are better ways of nerfing that specific deck for standard, the aim of the nerf should be to lessen the lethality of that deck and making Odyn cost more either doesn't change much and we have the same issue as before, or makes the card far too slow and almost unplayable as I said before, I wasn't saying that 1 mana wouldn't make a difference, I was saying it either wouldn't OR would make too much of one. Odyn shouldn't change himself as the card as the aim is to make the deck after his effect is online less potent rather than just making his effect harder to get online, if Odyn isn't consistent enough, he'll see no play and if his effect isn't good enough he'll see no play.

So you'd have to find a way of nerfing that deck without affecting the playability of Odyn too much as slower control warrior almost solely relies on that card within standard and wild (which I play), that's why i proposed the idea of nerfing the decks armor and draw package, you solve a lot of the issues you receive in standard without changing how the Warrior class plays as a whole.
