Rulings

From the Rosetta + 1st Strike release notes

When you destroy an aura controlled by you but owned by an opponent, it goes to their graveyard, (or ceases to exist if it’s a token).
You can only destroy an aura if you control an aura. If you didn’t destroy an aura you don’t get the Runechant token(s).
Deadwood Dirge may destroy a defending card you control with the aura subtype if it is played as an instant on an opponent’s turn.

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)
