Do you post this because you agree with the cause? It because you find it funny or absurd?
I personally agree with the ban.
Paradox Engine makes it far too easy to do broken stuff without forcing any color restriction. I don't think I've ever seen the card used in any kind of fair or fun way.
Edit: after reading the actual petition, I can see where they are coming from. I would still argue that Engine is rarely used fairly, but that could also be from the catch-22 such powerful cards often face: because it can be used in degenerate ways, opponents tend to assume it
will be used unfairly, and make you a target. So the only players who dare play it are the ones who abuse it.
Omniscience definitely suffers from the same problem.
