This card is unaffected by any effect other than its own, and after the Flash effect resolves, it is banished from the game.
Flash - Target as many opposing Spirits/Ultimates as you want. Exhaust all targeted Spirits/Ultimates, and these Spirits/Ultimates can't refresh for the rest of the game. Afterwards, banish all cards on the opponent's Trash. This effect can only be used during (Opponent's Attack Step).
