Planeswalkers' abilities are based on their loyalty, which is tracked with counters . A planeswalker card has a number printed in the lower right corner; this is its starting loyalty, and it comes into play with that many loyalty counters. The planeswalker's abilities each have a positive or negative loyalty cost; this is how many counters must be added (if positive) or removed (if negative) to play that ability. Abilities with negative loyalty costs may only be played if there are enough loyalty counters .
Each game represents a battle between wizards known as "planeswalkers", who employ spells, artifacts, and creatures depicted on individual Magic cards to defeat their opponents. Although the original concept of the game drew heavily from the motifs of traditional fantasy role-playing games such as Dungeons & Dragons , the gameplay of Magic bears little similarity to pencil-and-paper adventure games, while having substantially more cards and more complex rules than many other card games.
It's been more than a year since we last checked in on our Planeswalkers , and a lot has happened since then. We've seen unforgiving frontiers ruled by warlike khans, altered timelines, worlds ruled by dragons , the path of a predatory killer, and ominous glimpses into ancient threats nearly forgotten by time.
