Can a champion hide directly from the champion zone, or must it be in hand first?

Ruling: You will be able to hide from hand or champion zone in the updated rules. Currently, the rules are ambiguous, but the future ruling allows hiding from hand or champion zone, but not from other zones even if you're allowed to play the card from there.

Nuances:

• The current rules are ambiguous (one rule suggests hiding from anywhere instead of playing, another says from hand only)
• This is a future ruling that is not yet in the official FAQ
• For tournament play in China, ask a judge for current guidance
• For casual play, it's up to you and your opponent until the rules are officially updated
