Kicker 
(You may pay an additional as you cast this spell.)
If this spell was kicked, put a +1/+1 counter on a creature you control.
All creatures get -2/-2 until end of turn.
The Phyrexians were as surprised as anyone to discover they still needed to breathe.

If a spell's kicker cost was paid, the spell is "kicked."
(wotc • 2024-11-08)
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.
(wotc • 2024-11-08)
If a card or token enters as a copy of a permanent, the new permanent isn't kicked, even if the original was.
(wotc • 2024-11-08)
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.
(wotc • 2024-11-08)
If you put a permanent with a kicker ability onto the battlefield without casting it, you can't kick it.
(wotc • 2024-11-08)
The kicker ability doesn't let you pay a kicker cost more than once.
