Duck rarely goes off his pre-beaten path of magical creatures that base everything off of magic and simple tactics. An example would be the fact that a shield that covers an entire planet would take so much energy to resist an entire fleet's firepower would be so ridiculous, you might as well just make an energy shield projector and ENCASE the fleet inside of it.

Quite simply, you're screwed, I'm close to being screwed, let's all scream and die together, shall we?
