Odyn, Prime Designate needs to be reworked in my opinion. When I first saw this card revealed I thought that's a really good tool for control warrior. instead what we got is another deck where your opponent doesn't care about your board or your strategy and has the ability to otk you from hand at any point after turn 8.
Anyways I have a few different proposed changes that keep the card viable in a more controlling or risk/reward sense.
Change Battlecry to: For the rest of the game, after your hero gains armor, they gain that much attack for that turn, Once they've attacked they lose the armor gained.
Change Battlecry to: For the rest of the game, after your hero gains armor, they gain that much attack for that turn, Once they've attacked they lose all armor.
Change Battlecry to: For the rest of the game, after your hero gains armor deal that much damage to a random enemy minion.
I think the third option is the most reasonable and realistic.
I think Odyn is a terrible design for a card that was always going to be oppresive if it had a viable deck to fit into.
That said, based on how Blizz have dealt with similar cards in the past they're not going to nerf him. Best case scenario is they revert some of the many buffs they gave warrior and push the deck down in popularity. Most likelt scenario, they do nothing until the next expac then print something more OP that people use instead.
It would have made a lot more sense if Odyn’s battlecry meant that INSTEAD of armour gained, your hero gains attack. Not both. That way it puts the pressure on to close out the game quickly but does not mean you have 70+ hp and 25+ attack at once.
I think there are tons of viable routes to go. Some other alternatives:
For the rest of the game, after your hero gains armor, they gain 3 Attack for that turn.
For the rest of the game, after your hero gains armor, deal 3 damage to the enemy hero.
Once per turn for the rest of the game, after your hero gains armor, they gain that much Attack for that turn.
For the next 3 turns, after your hero gains armor, they gain that much Attack for that turn.
My only requirement for a good rework is that it's still good for Control Warrior. Right now I would categorize most Odyn decks as combo decks, they try to draw Odyn by turn 8 and then tries to win within a few turns before running out of cards. That is the best strategy because Odyn can end the game ridiculously quickly, very similar to The Jailer. I would much rather see Odyn play more like Alexandros Mograine or Sargeras, the Destroyer, a card that gives you a small/medium advantage over many turns rather than a humongous power spike that makes you autowin in 1-2 turns with the right hand.
Of course, a lot of the problem is Warriors unlimited, cheap AoE and removal. Huge problem. But, Id rather they leave Odyn as is but dial down the armor gain cards. Or, cap armor gain to like 10. Something like that. The card and deck is so stupid now. super easy to pilot and beats just about everything. Weapon tech does NOT help at all. Only huge taunts help and even thats dicey due to all the !@#$% removal.
The new AoE removal has killed any hope for a taunt based defence and also works really well to isolate a large minion for bladestorm. Also - the only decks running large taunts are controlish in nature. These decks have no ability to pressure in the early game so the warrrior has plenty time to assemble the removal and armour gain they need.
Imo this card needs changed, but it wont be changed :(
The paladin titan is the closest to a decent taunt available and even that dies rapidly to multiple warrior spells.
