Note that since the cards are banished face-down, any effects that rely on the card having certain characteristics (such as "Pot of Acquisitiveness" needing monsters) cannot be used, unless otherwise specified ("Gizmek Naganaki, the Sunrise Signaler").
"Number 89: Diablosis the Mind Hacker" can be used to either discourage the opponent from using this card or to banish at least 11 more cards from the opponent's Deck if this card have already been used.
If your opponent uses Pot of Desires, you can chain "Mystical Refpanel" to it to draw two cards while your opponent still has to pay the cost of banishing the top ten cards of their deck face-down.
