These cards have two parts
In the 8th environment in which this card appeared, Xyz Summoning was a common summoning method, so it was easy to aim for an RBI increase itself, but as time passed, various summoning methods and theme groups were added, making it an inefficient monster
It has enough consistency to play through an interruption or two, and sets up a diverse blend of interruptions and protections that make it just sticky enough to survive almost anything
Currently, the game is split between two major formats: Wanderer format, which allows play of every card aside from those from the Valhalla clusters, and ABC Format, meant to allow more players in one game
