Forum:I've got a question about /Assault Mode cards and my hand...

The way I understand /Assault Mode cards and Assault Mode Activate, the /Assault Mode version of the card has to be in the deck to be summoned by Assault Mode Activate. It can't be in the hand. Is this correct?

I'm trying to figure out if Assault Teleport is a waste in my deck or not, since Arcanite Magician/Assault Mode is one of the cards I'm trying to work with.
