From the Compendium of Rathe release notes

When an action with go again resolves, its controller gains 1 action point.
Multiple instances of go again on the same card or activated ability do not stack. If a card or activated ability has multiple instances of go again when it resolves its controller gains 1 action point only.

You cannot reveal a card with no to Belittle. The card must have a value to its power that is 3 or less. (0 is a value)
