Use multiples of this card to send multiple cards for each single time you deal damage.
Follow this card up with cards like "Drop Off" or "Drastic Drop Off" to make your opponent lose even more cards and force them into a bad position.
With "Toon World" on the field, use "Toon Gemini Elf", who can attack directly and can also make your opponent discard an additional random card when it attacks.
Out of all the 'hand destruction' cards available, this can be one of the most efficient. The majority of other hand destruction cards are one-use-only, but this can allow you deplete an opponent's options every time you inflict battle damage. During a prolonged duel where you've inflicted minor or major damage to the opponent multiple times, they will be hard-pressed to have any useful cards remaining in their hand for long.
In a Plant Deck, this card can combo with "Thorn of Malice" equipped to "Rose Tentacles" to effectively force your opponent to discard his hand if he has any Plant-Type monsters (including Tokens) to allow Rose Tentacles to deal piercing damage a few times with its own effect.
This card works well with "Reptiliannes" since they reduce monsters' ATK to 0 creating an easy means for dealing battle damage. "Fairy Box" can work similarly.
This card, when comboed with "Hard-Sellin' Goblin" while your opponent has no cards in his hand will create a combo that will destroy a Spell or Trap each time you inflict battle damage.
This card can work well with the "Watt" monsters. Assuming you can keep it on the field for a while, it can easily sway card advantage.
Despite this card's means of repeatedly generating card advantage, one reason why it is rarely seen in tournaments is due to the fact that a player will generally already be in a winning position to be taking advantage of this card's effect, and the card will do nothing to help a player in a losing position.
