Blood Sun

Oracle Text

When Blood Sun enters the battlefield, draw a card.

All lands lose all abilities except mana abilities.

1/19/2018 Land cards not on the battlefield aren¡¯t affected.
1/19/2018 If a land has an ability that triggers ¡°when¡± it enters the battlefield, it will lose that ability before it triggers.
1/19/2018 If 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.
1/19/2018 If a land gains an ability after Blood Sun has entered the battlefield, it keeps that ability.
1/19/2018 If 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.
