• 2024-11-08A landfall ability triggers whenever a land you control enters for any reason. It triggers whenever you play a land, as well as whenever a spell or ability puts a land onto the battlefield under your control.
• 2024-11-08A landfall ability doesn't trigger if a permanent already on the battlefield becomes a land.
• 2024-11-08Whenever a land you control enters, each landfall ability of the permanents you control will trigger. You can put them   on the stack in any order.
