When you hide a card like Flight or Fight using the Hide action, can it be played at action speed, reaction speed, or only reaction speed?

Ruling: Cards hidden with the Hide action gain reaction timing, which gives you permission to play them at reaction speed in addition to whatever other timing permissions they already have.

Nuances:

• Once a card is played, it no longer has a speed
• Timing permission is cumulative: cards with Reaction can be played when you have permission to play Actions, and both Actions and Reactions can be played when you have permission to play default timing abilities or take discretionary actions
