It's not stupid that Mard Geer made Natsu and Gray disappear before Face went of because even if they were to come back after face is activated they will still have a limited supply of magic power and once they are out they can't replinish their magical containers. Maybe Natsu can be flames is easy to come by but Ice isn't.
