this is my first post and I am not the forum kind of person, but yesterday while playing an abusive player occurred to me.
Player redacted asked me, after I plaied an Enchantress and he forgot to play a ruin to do such, by asking a three steo undo. Which I granted.
Then my mouse flipped, and let me play one coin token less, thus unallowing me to buy. I skipped a whole buy phase. I asked an undo, and he refused!
Then again, I plaied two times the same action although I clicked only one, and I asked to undo because I wanted to play an action between the two and again he refused.
So, basically, while he made a tactical error and I granted him to undo, when it was my turn that I just had a technical issue, and that was obvious, he resfused... I was really pissed off, as this made him win a head-to-head game.
I blacklisted him and I think such players ruin this game.
I understand (I barely do) a player who doesn't grant undos, but not a player who asks for them, then doesn't grant them. I think that's unfair, mean, and childish.
