Well we on our dutch forum play 3CB,
there is just something confusing
Random effects always go in your opponent's favour.
The thing is in who's opponent's favour.
I'd Say that it should be the owner of the permanent or spell generating the effect.
but others say it should be the opponent of the player controlling the permanent that generates the effect.
We stumbled up on this matter when someone became first by each game donating one of his permanent's which had a negative effect.
I then asked afther reading the rules how can he become first if his deck can't ever win.
to me it sounded obvious that this rule was about the owner... but what do you think ?
