Cool Card Design of the Day
4/20/2016 - I wanted to explore a mechanic like madness but without being an "A-B mechanic"—something that's only relevant when actively supported by another mechanic not already common to the game.
At first, Bitterness was just a flag: "If a card entered your GY this turn, this card is bitter." A kicker mechanic triggered by discard. Or mill. Or creatures dying. But keywords that do nothing on their own look dangerously strange. Was there some small bonus I could associate? I was working with sorcery-Shock. How about flash?
I went down that path long enough to find it's actually fairly
promising. The main trick being finding effects that are good after
combat because the only* game-inherent way to trigger bitterness is for
your creatures to die in combat.
It works on every card type but instant and planeswalker.
I'm still torn on whether effects that check whether bitterness is turned on should refer to it directly or not. Probably depends on finding a better word for mechanic.
* It occurred to me only as I was writing this up that casting a sorcery or instant puts a card directly into your graveyard, so all these cards inherently have a sort of prowess. While that dampens the flavor, I expect it improves the gameplay significantly.
