Remember that the effects are cumulative for multiple copies. By having two copies of this card on the field, your revived monsters gain 600 ATK, and by having 3, your monsters gain 900 ATK. This, coupled with a revival swarm, and two copies of the "Burden of the Mighty" card can overwhelm your opponent quickly. Just remember to leave some space for Traps in case of an emergency.
Use this card with "Athena" to bring back multiple Fairy-Type monsters each with 300 more ATK.
Use with "Dragon Queen of Tragic Endings". Not only will it aid in summoning and re-summoning her, it will also give her a 300 ATK boost when she summons herself from the graveyard, boosting her rather weak ATK.
