You can draw a random card at the Inn using Ancient Coins. Select a card to obtain Speed Up items, Hero XP items, or resources. There is a chance to obtain rare rewards as well.
The random cards will be refreshed every 24 hours, and you can refresh them manually using Gold 3 times each day. All rewards you can obtain from cards will be refreshed, including the rare rewards, when you refresh the random cards.
Tip: Refresh count resets each day.
