* You can take [[control]] of an opponent's [[Monster Card|monster]] first, then at the [[End Phase]] (since most cards that take control of monsters last only until the end of the turn) give back the monster with 2000 less [[ATK]] (a net decrease of 1000).
* You can use this card of on a [[DARK]] monster with an attack below 2000 but higher than 1000, that way before the End Phase, you can tribute it for the effect of "[[Deck Devastation Virus]]".
** You can also do the same except with a DARK monster with an attack less than 2500 but higher than 1500 and "[[Eradicator Epidemic Virus]]".
** Alternatively, you can use "[[Crush Card Virus]]" at the End Phase (Traditional Format only).
