Hi,

Good to know u r playing this game.

I suggest u level up Summoner and the team accordingly.

For example, I see you use WIZARD OF EASTWOOD.

For level 2, u need 5 more of WIZARD OF EASTWOOD

And you can use lvl 3 for common card, lvl 2 for rare, lvl 2 for epic and lvl 1 legendary card.

Then you upgrade you card accordingly, do not over upgrade.
