From the Dusk till Dawn release notes

You may target yourself. If you do, you may choose to fail to choose an attack action card, even if you have one in your hand.
The card chosen must be revealed. If the card can not be revealed (e.g. Channel the Bleak Expanse is in play), it is not put on the bottom of the deck and they do not create a ponder token.

Go again - Go again allows multiple actions to be played in a turn when usually playing an action with use up your action point, and therefore end your turn. A card with go again gives the controller of that card or activated ability 1 action point when it resolves.

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.
If an action with go again does not resolve, its controller does not gain 1 action point.
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)
