If a creature spell has kicker or multikicker and another ability that checks if it was kicked (such as Bog Badger or Phyrexian Missionary), that ability is linked to its own printed kicker or multikicker ability and will apply only if you paid its own kicker or multikicker cost. Sticker kicker won't turn on those effects. However, sticker kicker will work with cards that care about other spells being kicked, such as Elfhame Druid or Verazol, the Split Current.

Sticker kicker is an optional additional cost that you may pay as you cast a creature spell.

Conversely, you can't use sticker kicker to change a spell's name to get around effects that prohibit that spell from being cast (such as Meddling Mage).

If you put a creature onto the battlefield without casting it, you can't sticker kick it.

If you sticker kick a creature spell, you get and may choose a sticker to put on the creature spell.

Each Wicker Picker only lets you pay the sticker kicker cost once per spell. If you control multiple Wicker Pickers, then you can pay for each of them, gaining and a sticker each time.

If you cast a creature spell you don't own, you may still choose to sticker kick it. If you do, you'll get the ticket counter, even though you can't put a sticker on a card you don't own.

You get the ticket counter and the sticker is put on the creature spell just before it's considered cast. Any triggered abilities that trigger whenever you cast a spell with particular qualities will see the spell with the sticker applied.

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.

If you put a permanent with a kicker ability onto the battlefield without casting it, you can't kick it.

If a card or token enters as a copy of a permanent, the new permanent isn't kicked, even if the original was.

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

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.

If a spell's kicker cost was paid, the spell is "kicked."
