Ok so, first make sure you put the kraken card into your deck. Then right click on one
card to discard a card. You can dicard one or more cards. There will be a smaller amount
of that card if you discard one and you put more than one in ( sorry if i said that wrong
xd ). That also depends if you put more than one of that same card in. If it's a treasure
card, dicard one treasure card and click draw. The kraken card will appear. Make sure you
put it in your deck first. :)
