Kicker
(You may pay an additional
as you cast this spell.)
When Thicket Elemental enters, if it was kicked, you may reveal cards from the top of your library until you reveal a creature card. If you do, put that card onto the battlefield and shuffle all other cards revealed this way into your library.
The “if you do” means “if you choose to reveal cards”. You still shuffle if you have no creature card in your library.
