Blue Sky Knights, Drum the Tempest/Tips


 * Call this card while you have Blue Sky Knights, Systemic Dagger Dragon on the field, it'll activate Systemic Dagger's effect, which in turn will activate this card's effect so you draw two cards and gain two Life at once.
 * Counter cards that increase your Life such as Green Dragon Shield work very well with this card since its effect also activates during the opponent's turn.
