Unless the effect says something like "in addition to its other types" like Urborg, Tomb of Yawgmoth, a land that becomes a basic land type will lose all other abilities and will only have the mana ability granted to it by that basic land type (This is why Blood Moon was so popular, it really messes up your opponent's ability to do stuff with lands). So Yes, this includes abilities like Thespian's Stage, as well as other land abilities like Reliquary Tower's hand-size effect or other miscellaneous land abilities.Oh, btw I didn't notice this was in the wrong forum at first. Rules Theory is the place where you'd discuss How or Why Sea's Claim does what it does, and whether or not the rule might be changed or other abstract stuff like that. For simple questions about what will actually happen in-game when you play the card, just go to Rules Q&A. They're much faster to respond, too.

Dual means two. A duel is a battle between two people. Lands that make two colors of mana are dual lands. A normal Magic battle is a duel.
