I just ran into a bug. I found a ring that makes each player generate a random effect each main phase or something. My opponent got the effect “Gain 5 life.” Well, my opponent is just gaining and gaining and gaining 5 life over and over again. It’s up to about 2000 now. See the screenshot I took:

Oof, I'm very sorry to hear that you encountered such an annoying bug, I'll try to take care of it asap!
The equips are a very fresh addition to the game and I couldn't test every possibility, this seems like a very silly and easy to fix bug. I will also fix the active and passive mishap.
I'm glad to hear that you are otherwise enjoying it!
