This card has great synergy with "Obliterate!!!", as the latter can send "Forbidden One" cards to the Graveyard to bounce monsters your opponent controls while powering up this card at the same time
"Exodius the Ultimate Forbidden Lord" can similarly assist this card by sending monsters to the grave each turn. Also if one monster should fall the other can serve as a backup plan.
If there is time to stall for getting the five pieces of "Exodia" to your hand from your Graveyard, a good strategy is to have multiple copies of "Magician's Valkyrie" on the field to create an attack lock.
