For Challenge # 040. Valkri is the setting of my set Convergence. The Turbulence is a type of uncontrollable mana that does chaotic things to your spells.

Rules-wise, if you copy a permanent spell, you end up putting a copy of that permanent onto the battlefield under your control.

I really like the concept, but I have to ask:
Is anyone ever going to want to roll while on this plane?

You would want to roll to make others stop copying your spells, I guess. But you're right, there's a strong incentive not to roll.

No one would want to leave, but the chaos ability is very powerful, especially with many players. For each spell cast that way, you get the copy as well. If people roll for chaos, they'll eventually planeswalk away.

Oh, you're right. I didn't notice that. My bad.

So... if I'm winning, I never want to roll or cast spells. That would result in bad things, since my opponent must either (1.) Roll to get out of Valkri, or (2.) Cast spells, which I immediately get copies of and keep winning.

Also, if both my opponent and I perceive that we are both winning, neither of us rolls or casts spells. We just sit, draw and pass.

Does that sound about right?

The chaos ability on most planes is beneficial. This is horribly detrimental. Which means that if someone's suffering from the main ability, they'll want to be rolling to try to get away, but the chaos ability will be punishing them even more than the inherent "roll blanks 2/3 of the time" factor. I don't like it.

Also, "you" on a plane refers to the player whose turn it currently is, right? Which means the top ability doesn't do very much except nerf countermagic and defensive combat tricks.
