Rulings

• 2024-11-08 · Wizards of the Coast
  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.
• 2024-11-08 · Wizards of the Coast
  If you put a permanent with a kicker ability onto the battlefield without casting it, you can't kick it.
• 2024-11-08 · Wizards of the Coast
  If a spell's kicker cost was paid, the spell is "kicked."
• 2024-11-08 · Wizards of the Coast
  If a card or token enters as a copy of a permanent, the new permanent isn't kicked, even if the original was.
• 2024-11-08 · Wizards of the Coast
  If you copy a kicked spell on the stack, the copy is also kicked. If the copied spell is a permanent spell, the token the copy of that spell becomes when it enters is also kicked.
• 2024-11-08 · Wizards of the Coast
  The kicker ability doesn't let you pay a kicker cost more than once.
• 2009-10-01 · Wizards of the Coast
  You can tap a creature that hasn't been under your control since your most recent turn began to pay the kicker cost.
