Card Tips:Vain Betrayer
- This card can be searched by "Pharaonic Advent", "The Despair Uranus", and other generic searchers.
- This card can be used in Decks like "Iron Chain" cards and "Empty Jar" to both protect your monsters from attacks and mill your opponent's Deck even more.
- Against Decks that are extremely reliant on Xyz Summoning, this card can be devastating. If they attacked with a particularly powerful Monster such as "True King of All Calamities", their efforts will have been a serious waste of potential.
- In a "Lockdown" Deck, you can lure your opponent to Xyz Summon a monster by using Level-related cards like "Gravity Bind", "Level Limit - Area B", etc. in order to use this card.
- Combo this card with "Vampire Kingdom" to destroy 1 card on the field during each of your opponent's End Phases, assuming you have "Vampire" monsters to send.
