Expulsion is an Integrity deck specific effect card. It allows the owner to put an enemy card back into the opponent's hand, making it work like Endogeny, but without being randomly chosen.

This can be useful for removing taunt cards from play or to make the opponent have a full hand, making them lose the next drawn card. It can also be used to kill the targeted monster if the opponent already has a full hand.

Keep in mind that returned cards will be turned into their base form and that Magic and Future effects can be re-activated.
