1-9 | You may put a land card from among those cards onto the battlefield.

10-19 | Create a 2/2 green Wolf creature token, then put a +1/+1 counter on it for each creature card among those cards.

20 | Put all permanent cards exiled with Journey to the Lost City onto the battlefield, then sacrifice it.
