Swivel

Swivel is a Skill for the Watcher. It gives 8 (11 if ), as well as 1 stack of the Free Attack Power buff, which makes the next Attack played cost 0 .
== Mechanics ==
* Free Attack Power buff is a stackable buff that makes all Attacks cost 0, and 1 stack is removed each time an Attack is played. Multiple stacks can be gained by playing Swivel multiple times without playing any Attacks. 
**Even if the Attack played already costs 0 (e.g. ), a stack of Free Attack Power is still used up.
* Free Attack Power does not expire at the end of the turn.
*When using an Attack that costs X with Free Attack Power, X is still equal to current Energy. However, no Energy is spent after playing the card.

** As a result, Swivel can also fit well into a deck using the .
