An OTK can be performed with "Brionac, Dragon of the Ice Barrier", this card, "Card of Safe Return" and a card such as "Mass Driver" or "Cannon Soldier". Activate this card, Special Summon a monster from the Graveyard, draw a card, discard that card to bounce this card, and then Tribute the Summoned monster for "Mass Driver". Repeat for the OTK.
