New Keywords!

I've started playing with ideas for a custom expansion, or even a custom year, but I thought I'd sound out a couple of the keyword ideas I had for the first one, before designing a set around them, only for them to be hated. So. here they are:

They are designed to be used in different deck designs, with Bully obviously being an aggro-centric ability, rewarding the player for taking the initiative, while Underdog aids the player in regaining control, surviving, or holding the game until they can produce a swing turn.

My concern here is that this mechanic would be polarising - If a control deck runs Underdog cards, they're stronger against Aggro, while weaker against other control decks. Likewise, Aggro decks that rely on Bully might find their plan undone by an aggro mirror, where their opponent doesn't run bully cards.

So....thoughts? Please?

All things in moderation.

If you are careful with what you put these mechanics on, and what they payoff is, then it should be okay. You mentioned being worried that if you get paired against the wrong archetype then it can ruin your strategy. To get around this, don't implement these keywords in a way so that your deck is built around them. Also, this could be a good thing. If you are aggro vs aggro running bully cards, then you might have to shift your strategy a bit to stay ahead of your opponent in terms of life total.

I think this mechanic is really cool. I fully support anything that makes your health total more relevant. By that I mean, something that gives you more of an incentive to heal your face that isn't simply prolonging your demise.

Underdog effects would fell like quest priest.. I hate being punished for executing most deck's game plan

Also bully is too much of a win more...

I don't like the implications of those mechanics specially since they are not consistent from game to game and polarizing based on early game.

I like the hp threshold mechanic on warrior and warlock though.

Would suggest that you should make those effects about your life total in general not compared to your opponent. 

I dont think this mechanic is even a good idea. You can just ping out enemy health or restore your health little bit and you gain strong effect. I would prefer to keep it as below or above 15 health, but that would sorta take away warlock and warrior identity/style if used for all classes. Probably the identity or style is not that important nowadays.
