Magic The Gathering Thread XXIII: Modern is Dead, Long Live Modern

[enderlord99]

Spreading Seas reads:
"Enchant land
When Spreading Seas enters the battlefield, draw a card.
Enchanted land is an Island."

and the ruling below clarifies "The enchanted land loses its existing land types and any abilities printed on it. It now has the land type Island and has the ability to tap to add {B} to its controller’s mana pool."

So unless I missed something it should work the way I origionally worded it.

You missed something. Island is a subtype; Waste isn't.
