How is Satan Bound?

A HUGE issue with Amillennialism is that Satan is currently bound from deceiving during the Church Age. However, multiple scriptures warn us to not be deceived by Satan and tell us to guard ourselves against his schemes. So how does one reconcile (Amillennialist or not) Satan being bound in Revelation 20? Could Satan just be currently "bound" from starting Armageddon, yet still able to deceive believers? This is a sound clip from episode 393 of Naked Bible Podcast.
