i know it sounds kinda weird , but can there be a system that lets us shuffle cards in the deck?
like when we start a match , the number of cards we have in our deck is shown right next to our health bar .
if we are not getting the cards that we want(not enough pillars or the requires shields or the golem/spirits etc) we could click a button that would shuffle the cards in our deck randomly!!
ps - this is just a thought!
