Each of those packs enables you to start playing Corunea RCG. You will get all the cards you need to taste 2 very different classes.

Starter Pack 2 * Swordmaster & Defiler

If you get 2 starter packs for yourself plus another player, we recommend to choose 2 different ones.
The starter packs numbers are just a way to identify them clearly, you don't need to get the starter pack 1 first, you can start with the number 2 or 3.
It is possible to start playing the game with only 1 starter pack for 2 players, but you will then need a minimum of 4 additional booster to have enough cards to build 2 decks.
Each starter pack contains the complete rules of the game, both in English and French.
