- You can use cards like "Lightning Vortex" with Discard costs and easily get your cards back with this effect.
- Use "Hand Destruction" to make you and your opponent discard two cards. You discard two Batteryman monsters to Draw two cards and use this card to get the cards you discarded back while your opponent gets only two new cards and loses two cards. (Problem being you use two cards to do this, so there's no overall gain)
