The idea

The League of Legends card game. You bring a Legend, a 40-card main deck and a rune deck. Runes make the energy that plays units and spells. Units fight over battlefields, holding and taking them scores points, and the first player to the point target wins.

Your first game

The Proving Grounds box has four ready-made decks and the battlefields, so up to four people learn in one sitting. Play a unit, move it to a battlefield, hold it through your opponent's turn.

What to buy next

A Champion deck for the Legend you like, then singles as the set grows.
