The story behind the MTG War of the Spark set has been serialized on the official page. It seems to be published every Wednesday (Thursday, Japan time). On this page, I will read through in a row, I will summarize the general flow, even characteristic events. It is a summary mainly for myself. Please refer to the official page for details. All card images are quoted from CARD GALLERY (link).
At the guild’s promenade, the conversation between “Rat (Araithia Shokta): born gruel” and “Hekara” “Hekara” had been ordered to monitor Ral Zarek in a raid of the Rakdos, and asked “Rat” for strength.
Shield Mage “Tayo” comes through a plane’s walk and meets “Rat”. The first plane’s walk of “Tayo”. Each guild tried to unite in order to defeat the situation by “Rat”, “Nichol Vorras”, but they are confused by “Isperia (Azorius guild master)” by “Vlaska (Golgari group guild master)” .
Torn the Guildpact building in two, “Nicole Bolas” appeared.
Starting with “Liliana”, a war group appears and a slaughter occurs. “Tayo” “Rat” “Ral Zarek” “Kaya” “Jace Beleren” “Lavinia” “Gideon Jura” “Tefeli” “Chandra Nalaar” “Jaya Ballard” “Ajani” “Karn” in cooperation Stand up to the war crowd. “Ajani” I am impressed by the sense of solidarity and gives a jealousy. It is misunderstood as “Teyonraht” (Tayo and Rat).
Ask each guild for cooperation. However, “Gorgali”, “Azorius” and “Grull” have fallen to “Bolus”. It is told that “Hikara” is dead.
