You can win Health Boosts for each of your clans by playing Training Games. Use the Health Boosts in battle to restore some of your hybrid's health, letting you stay in the fight longer.
To use a Health Boost, click the Health Boost icon when it is you turn. The number on the icon will go down, showing you how many Health Boots you have left. When you've used all your Health Boots, the icon will disappear.
Any Health Boots you use in a fight will be used up forever, but any you don't use will carry over for other members of the same clan to use in the next fight. Be sure to use them wisely!
For Version 3.0 or higher users ONLY: As you continue to purchase packs, you will unlock cards for your match card collection. To see which cards you already have, go to the match game and tap the Thomas icon in the bottom right corner of the screen. From here, you can view and interact with your cards, or purchase more for your collection!
