Enchantment — Aura

Enchant land
When enchanted land becomes tapped, destroy it. That land's controller may attach Kudzu to a land of their choice.

You can move it to any other player’s land whenever you get to move it.

If Kudzu is destroyed directly, or the land is destroyed by a spell or ability, then Kudzu goes to the graveyard like any Aura would.

The controller of the destroyed land must attach it to another land if possible. If there are no valid choices, Kudzu is simply put into the graveyard.

Because the ability isn’t targeted, the controller of the destroyed land may attach it to a land that can’t be the target of abilities.
