Aside from stats and abilities, the cost to play a card can make a big difference. Understand that there are just some cards you won't be able to give to your favorite hero. Each hero is limited to two card types, which can vary wildly from character to character. Heroes can only use specific card types.If you have several low-cost weak cards of different types, consider hanging on to the ones that would benefit from this sort of enhancement. Some cards give boosts to specific cards like Science Zombies or Mushrooms. Some cards will play well off of others, giving you some pretty fantastic opportunities if you have the right sets available. Think carefully when adding or removing cards. The deck you use makes an even bigger difference than your chosen hero.
