Urborg Repossession

The kicker ability doesn't let you pay a kicker cost more than once.

To determine a spell's total cost, start with the mana cost (or an alternative cost if another card's effect allows you to pay one instead), add any cost increases (such as kicker), then apply any cost reductions. The spell's mana value remains unchanged, no matter what the total cost to cast it was.

You can't cast Urborg Repossession kicked if there aren't both a creature card and another permanent card in your graveyard.

If it isn't kicked, Urborg Repossession has only one target.
