When you start this App insert your friends referral code and then both you and he can get 1rare card and 10,000 coins.
Save your unbound Energy and Power Potions. They are the money of the game and that is how you get good cards and succeed in the game.
Get into a good guild as early as possible.
Make friends…not only do you get extra stat points but when you need help most people are friendly enough to help you.
At first dump all of your stat points into Energy,until you get at least 100,you will level up a lot faster thereby getting you up in levels very quickly and then you get a LCP Ticket (Legend Card Pack) which gives you a real (free) chance at getting a very good card.
In my personal opinion but also a helpful hint “DON’T SPEND REAL MONEY ON THIS GAME.” It may take a little longer to get good cards but you can do it without spending any real money.
Be active and help your guild and will get better and better cards.
Last and least type in my referral code : YellowJack after you complete the tutorial and you (and I) shall receive 10,000 coins and a free rare card.
