Rulings

From the Uprising release notes

When Double Strike leaves the combat chain this way, its chain link remains and is still considered there for the purposes of abilities and effects like Rupture.
You still control the chain link, but do not control the card when Double Strike leaves the combat chain.
The chain link resolves immediately after the damage step of combat.
When Double Strike is put into the banished zone, it becomes a new object separate to its previous existence. Effects that applied to its previous existence do not continue to apply to the card, including when it is played from the banished zone.
When Double Strike is put into the banished zone this way, it only loses it the triggered ability; it retains the Go again ability (for the second time you play it).

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)
