Notes and Rules Information for Xucro Cáustico:

• Only the English version of a Magic card receives Oracle updates and errata. View this card in English. (Scryfall note)
• If the revealed card doesn’t have a mana cost (because it’s a land card, for example), its mana value is 0. (2024-04-12)
• If the revealed card’s mana cost includes {X}, X is 0 for the purpose of determining its mana value. (2024-04-12)

• If Caustic Bronco isn’t on the battlefield as its triggered ability resolves, use whether it was saddled or not before it left the battlefield to determine who loses life. (2024-04-12)
• “Saddle N” means “Tap any number of other untapped creatures you control with total power N or greater: This permanent becomes saddled until end of turn. Activate only as a sorcery.” (2024-04-12)

• “Saddled” isn’t an ability that a creature has. It’s just something true about that creature. It won’t stop being saddled until the turn ends or it leaves the battlefield. (2024-04-12)
• Creatures with saddle can attack or block as normal even if they aren’t saddled. (2024-04-12)
• If a permanent becomes a copy of a saddled Mount, the copy won’t be saddled. (2024-04-12)
• You may activate a permanent’s saddle ability even if that permanent is already saddled. (2024-04-12)
• An ability that triggers when a creature “attacks while saddled” will trigger only if that creature was saddled when it was declared as an attacker. (2024-04-12)
