Rulings

From the Compendium of Rathe release notes

When Look Within resolves, you will search your deck for a card with the Chi subtype, reveal it, shuffle, then put it on top of your deck.
When searching your deck for a Chi, you can fail to find a Chi even if you still have one in your deck. Nothing is revealed nor put on top of your deck; however, you will still shuffle your deck afterwards.
When resolving Look within, there is no priority between any of the effects generated (e.g. searching, revealing, shuffling, putting it on top of your deck)

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.

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)
