6 rulings from Wizards of the Coast
- 19 January 2018If a land has an ability that triggers “when” it enters the battlefield, it will lose that ability before it triggers.
- 19 January 2018If a land has an ability that continuously changes the types of other lands (such as Urborg, Tomb of Yawgmoth does), that ability will apply before Blood Sun removes that land’s abilities. If a land has an ability that grants abilities to other objects, Blood Sun will stop it from doing so.
- 19 January 2018Land cards not on the battlefield aren’t affected.
- 19 January 2018A mana ability is an ability that produces mana, not an ability that costs mana.
- 19 January 2018If a land gains an ability after Blood Sun has entered the battlefield, it keeps that ability.
- 19 January 2018If a land has an ability that causes it to enter the battlefield tapped, it will lose that ability before it applies. The same is also true of any other abilities of a land that modify how it enters the battlefield or apply “as” it enters the battlefield, such as the first ability of Unclaimed Territory.
