Since the cost is low, you might want to make a fail-rate.
I kept the cost this low because using this properly will require at least two cards or a situational play from the opponent for it to be useful (like casting antimatter or alfatoxin on you). But I guess since it's generic quanta, a 3 | 2 cost won't be so bad. If that sounds more fair, I can change it. Fail rate dampens the mechanic somewhat and also doesn't gel so much with Darkness.
isn't it too cheap, though?? idk..
It definitely can be cheap if we also create some deadly debuffing creatures / permanents along with it. Fortunately, right now I do not see any OP combos in the already released cards (though there are a couple of Crucible ideas that can easily be OP with this card).
i have actually been working on an entire series that uses this basic idea if used right it could be mean

Oh nice, I would love to see what you've come up with. I definitely think this mechanic has a lot of potential for adding a whole new layer to the game. I've also been churning some ideas that would work with this, but I wanted to post this FIRST so that the mechanic is established. That way, knowing that there is a way to easily give creatures or permanents to your opponent, it would be easy to design balanced debuffing cards in the future.
