Card Game Mechanics
Every card has a coin cost to play, and your goal is to reduce your opponent's coins to zero while keeping yours intact. 
You and your enemy's coins will be displayed at the top of the screen during a battle.
When battling an enemy use the mouse to select the cards you would like to play then press the "End Turn" button at the bottom left of the screen.

Tips:
Look for treasure chests in the dungeons these contain spare coin and powerful cards!
Golden chickens are pretty defensive so battling them can be a golden opportunity to win more coins. 
Cards that apply an effect to the next card can be used at the end of the turn to power up the next card you play on your next turn.
