One thing you need to understand from the very start is that where you place your champions at the start of each match is going to have a pretty big effect on the outcome of the game. That's because they have different abilities that trigger against certain lanes. Pressing on a card will show you the skills it has, and the powers it'll unlock when you complete all of its challenges (more on those in the next entry). You also need to think about what your opponent has placed where, and how the champions you've got might be able to deal with that threat.
