Hello, I was playing Munchkin last night and a friend of mine drew a card with an effect that triggers "When this card enters battle."

I forget what the exact context was, but he was going to lose two equipped items because of it.

Now, he had an item that would change the effect of any monster, and wanted to use it to get his two cards back.

Would he not still lose those two cards because the effect of the monster was instant?
