Les trois cartes Dispeller's Capsule, Courier's Capsule et Executioner's Capsule, de l'édition Shards of Alara, forment un cycle appelé "Capsule" d'artefacts colorés dont les couleurs combinées correspondent à celles rattachées à Esper, un des cinq éclats d'Alara.

Source ("Each of the five shard design teams was going to have a significant amount of autonomy to figure out their own shard. The one rule we had to follow was this: each shard could not know of the four other shards, meaning that everything from that shard had to make sense in that shard. [...] The idea Bill had was that he wanted each shard to flourish independently, just as the shards would in the story.")
