This single strike is the righteous anger of the knights.
[CONT](RC):During the battle that it boosted, if you have a vanguard with "Blaster" or "Arc Saver" in it's card name, this unit gets [Power]+2000.
[AUTO](RC):When it boosts, if you have six units with "Blaster" in their different card names, choose a rear-guard in your opponent's front row, and bind it.
