This card bypasses the usual pitfalls of costsand destruction effects. It essentially has two effects. The first targets your monster when its activated. The second--which only activates after your oppoent is done chaining (if they bothered)--tributes your monster and targets/destroys an opponent's. So, your opponent can't use effects like Prime Material Dragon or Stardust Dragon (since nothing will be destroyed immediately). And, if your opponent negates this card, you don't tribute. However, keep in mind that continuous effects still apply. (I.E. You can't target a dragon with Lord of D. on the field.)
Attack with the Normal Monster you choose for this card's effect before you use Order to Charge. If your opponent has two monsters (at least one weaker than yours), you can potentially destroy two in one turn.
