Waste Management
Instant
Kicker 
(You may pay an additional as you cast this spell.)
Exile up to two target cards from a single graveyard. If this spell was kicked, instead exile target player's graveyard. Create a 2/2 black Rogue creature token for each creature card exiled this way.

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."
(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.

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.
(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)
Waste Management's controller will create a 2/2 black Rogue creature token for each creature card exiled this way whether it was kicked or not.
