Kajtou, Llamaworm Techy

When Kajtou, Llamaworm Techy
enters the battlefield, you may reveal cards
from the top of your library until you reveal a creature card with converted mana cost 3 or less.
You may cast that card without paying its
mana cost. Put the rest of the revealed cards on
the bottom of your library in a random order.
