Axe Cop: Queen of England

[harlomcspears]

The "Queen of England" card reads as follows:

Play at any time on your turn. The Queen grants you a Power; Until the end of your turn, this power counts as Rank 0. Usable once only.

Where are you supposed to get "a" Power from? There seems to be several interpretive options, and we don't know which the card intends:

1. You can now use a power you have played but which exceeds your level.
2. You can take a power from the discard pile.
3. You can simply give yourself a power that you know to exist in the game.
