Re: Forge Beta: 10-03-2014 ver 1.5.28
I've just had this situation in a game.
On my turn I played Urborg, Tomb of Yawgmoth. On the AI's next turn it cast Lingering Mirage on my Urborg, Tomb of Yawgmoth which became an island. But as you can see on the card detail panel on the right side the opponent's island which I've highlighted is still a swamp in addition to being an island. It's the same for my two enchanted swamps. Urborg, Tomb of Yawgmoth itself stopped being a swamp. Shouldn't the opponent's islands and my enchanted swamps stop being swamps as well?
Edit: After reading the card ruling for Urborg, Tomb of Yawgmoth it seems to be correct that the other lands are still swamps in addition to their other types.
What happened in the next turns: I played another swamp which then was enchanted by AI's Spreading Seas. That swamp just became an island and I couldn't tap it for black mana anymore (unlike my other enchanted swamps). Since it was on a different turn I think the part of the ruling which I've put in bold doesn't apply and it works correctly (?).
Ugh, these interactions seem complicated.

The type of the enchanted Urborg, Tomb of Yawgmoth is "Legendary Land - Island". According to the ruling it should be "Legendary Land - Island Swamp" though (without being available to tap for black mana). (Even though it's probably not that important in most situations if Urborg, Tomb of Yawgmoth is still a swamp or not.)2/1/2007: If Urborg loses its abilities (for example, it becomes a creature and then Ovinize is cast on it), all lands on the battlefield, including Urborg, will still be Swamps, but Urborg won't have the ability "Each land is a Swamp in addition to its other land types." Urborg also won't be able to tap to produce, but other lands (including those that enter the battlefield later in the turn) will. The way continuous effects work, Urborg's type-changing ability is applied before Ovinize removes both the type-changing ability and its own mana ability.
