Forum:Cross Counter Q

Howdy!

Here's a question regarding the card "Cross Counter." For those who aren't familiar with it, here's its effect:

"If the DEF of an attacked Defense Position monster is higher than the ATK of your opponent's attacking monster, the Battle Damage inflicted to your opponent is doubled. Destroy the attacking monster after damage calculation."

First off, this card doesn't say exactly when you can activate it, so let's pretend you activate it when one of your defense position monsters is attacked with a DEF that is actually lower than the ATK of your opponent's attacking monster. Sure, your defense position monster is destroyed, but the card's second effect says, "Destroy the attacking monster after damage calculation." Is this working how I think it's working?

Does this card function as another Sakuretsu Armor, only it destroys your opponent's monster after the damage calculation?

Thanks in advance for the answer, everyone!
