Welcome to Eternal! The following is a guide to help get you on your way to building a collection and competing on the ladder (Ranked) as well as an introduction to the AI modes of Eternal (Gauntlet and Forge).

This guide assumes you have completed the tutorial, and have all the modes of play unlocked.
