Use this card with "Shien's Spy" and "Breakthrough!", destroy this card while it is on your opponent's side of the field and during its destruction, you are able to special summon an extra monster to attack directly w/ your opponent.
This card can be used in combination with "Creature Swap" in order to take control of a strong opponents monster, then attack "Shien's Footsoldier" and special summon a "Six Samurai" monster to attack with him again.
Also this card can be used while "Desperate Tag" is on the Field to summon 2 "The Six Samurai" monsters.
If you choose to attack an opponents monster with higher ATK to take advantage of "Desperate Tag's" effect, try to have a "Miracle's Wake" or any other card ready that'll allow you to summon "Shien's Footsoldier" from your graveyard to repeat the process and gain up to 2 more Six Samurai Monsters in the same turn.
