Does Loose Cannon's ability go to Chain if you have 2+ hands, allowing you to play Reaction cards to reduce your hand size before drawing the additional card?

Ruling: Yes, Loose Cannon's ability goes to Chain even if you have 2+ hands. You can play Reaction cards to reduce your hand size before the ability resolves and draws the additional card.

Sequence:

• The ability triggers at start of beginning phase regardless of current hand size
• The ability goes to Chain
• You can play Reactions to reduce your hand size
• When the ability resolves, it checks the condition (1 or fewer cards in hand)
• If the condition is met at resolution, you draw the additional card

Nuances:

• This works differently than abilities where the condition is part of the trigger condition (before the comma), such as Sunken Temple which requires a mighty unit as part of the trigger itself
• The timing differs from cards like Rocket which don't trigger when in hand
