A Special Force consisting of those who are exceedingly loyal and faithful to the Dragon Empire, and are chosen from the ranks of the "Narukami" clan, one of the two major Military Wings of the Dragon Empire. As what the title literally means, the aim of the force is to "Eradicate" anyone who dares to make an enemy out of the Dragon Empire. All are subjected to a special training so that they can make ruthless choices during their mission, no matter how peaceful one acts when they're off duty. In addition, only the upper echelons and those who belong to the "Eradicators" know who's appointed to bear the title of "Eradicator."
Who are the "Eradicators"? (December 10, 2014)
In the past, it is a Special Force consisting of those who are exceedingly loyal and faithful to the Dragon Empire, and are chosen from the ranks of the "Narukami" clan, one of the two major Military Wings of the Empire. Now, the belief and the composition of the force has changed from when it was established, with only its name remains unchanged. The fact that no great war has occured these days reduces the number of secret missions, leading to the dismiss of many forces, but "Eradicators" manage to continue the existence of the force. It changes from a discretely-working troop to a jack-of-all-trade special force which accepts all types of tasks. The fame of the legendary special force "Eradicators", though earned from past glory, is beyond one's creativity could possibly dreams of, and it is told that there are always applicants queuing up. And by so the new "Eradicators" succeed in reforming greatly, reborn into one of the largest troop of "Narukami".
Playstyle
Eradicators much like the clan they derive from focus primarily on the removal of the opponent's front row rear-guards via retiring them through unit effects which can also lead to certain benefits for specific units such as increased [Power] , [Critical] or even drawing cards based on the amount of rear-guards that are retired. Overtime, the sub-clan would go beyond retiring the front row to retiring any of the opponents rear-guards on the field at the opponent's discretion or even unit effects that retire all rear-guards, both the players and opponents that are present on the field.
With the G Standard format, Eradicators as a sub clan would receive further support emphasising on it's penchant for retiring while also expanding on several of it's vanguard units who would form their own archetypes. This would come in the form of the Gauntlet Buster archetype which centred around Eradicator, Gauntlet Buster Dragon's where it garnered additional [Critical] and [Power] for each instance an opponent's rear-guard was retired via the player's effects and the Descendant archetype which follows the theme of Eradicator, Dragonic Descendant's by having skills that activate based on whether a unit's attack hit or didn't hit as well as skills that activate when the vanguard attacks, offering synergy with Descendant and it's subsequent forms ability to [Stand] at the end of battle.
Re-introduced as a sub-clan much later in the V Premium format, the sub clan follows closely to Narukami's penchant for binding the rear-guards of it's opponents with a significant portion of Eradicators also being able to move the opponent's rear-guards from the backrow to the front row, allowing for more opportunities to affect the opponent's field. The sub clan centres itself primarily around Eradicator, Dragonic Descendant's ability to copy the skills of any Eradicator unit it rides over, allowing for powerful skill combinations when put in tandem with it's ability to [Stand] at the end of battle.
