[Truper]

There were 5 global enchantments active in the world. One was the Eyes of God. I cast fate of Oedipus, which duly destroyed the Eyes. The next turn, I cast Mother Oak while there were only 4 globals active. I got a message that my enchantment was overpowered by the existing enchantment and failed to take effect (even though I'd used 30-some-odd extra gems!). No other global was cast the same turn, and there are still only 4 active.
