<Snipped quote by DarkwolfX37>

Well, it's a bit more than an illusion. With an illusion, a smart character can go, "Wait, this doesn't make sense. It can't be real." They can then try to figure out a way to see through it. However, by altering the semantic identity of an object, you are forcing every character to think X = Y. They will think and act as though the illusion is real regardless of how little it makes sense. 

For example, she could switch the semantic identity of her team's flag and a leaf. Now, the entire team will be trying to capture the leaf and ignore the flag.
