  Some instant or sorcery spells require alternative or additional targets if they’re kicked. You ignore these targeting requirements if those spells aren’t kicked, and you can’t kick those spells unless you can choose the appropriate targets. On the other hand, you can kick a permanent spell even if you won’t be able to choose targets for an enters-the-battlefield ability of that permanent once the spell resolves.

  If you copy a kicked spell, the copy is also kicked. If a card or token enters the battlefield as a copy of a permanent that’s already on the battlefield, the new permanent isn’t kicked, even if the original was.

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

  You can’t pay a kicker cost more than once.

  Because targets are chosen as you cast a spell, you can’t have Inscription of Ruin return a creature card and then destroy that creature.

  If more than one mode is chosen, perform them in the order written. Nothing can happen in between, however, and no player may choose to take actions. Any abilities that trigger will be put onto the stack after the spell has finished resolving.

  Kicker represents an optional additional cost that you may choose to pay as you cast the spell. A spell cast with that additional cost paid is “kicked.”
• 2020-09-25
  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 converted mana cost of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.

  If you kick Inscription of Ruin, you can’t choose any one mode more than once.

  If a card in a player’s graveyard or a creature on the battlefield has in its mana cost, X is considered to be 0.

  If any targets become illegal, the other targets will still be affected as appropriate.

  An ability that triggers when a player casts a kicked spell resolves before the spell that caused it to trigger, but after targets have been chosen for that spell. It resolves even if that spell is countered.
