In a Jinx mirror match, if I have 1 card in hand and trigger Jinx's legend ability to draw at the start of my beginning phase, can my opponent react with Gust on my unit before I score for holding?

Ruling: Yes, your opponent can react with Gust before you score for holding. Jinx's legend ability enters the chain every turn, giving your opponent priority to play reactions before the hold scoring condition is checked.

Sequence:

• Jinx legend ability triggers at the beginning phase (315.2.a)
• Jinx ability enters the chain
• Opponent gets priority and can play Gust as a reaction
• Hold scoring is checked afterward (315.2.b)

Nuances:

• This works regardless of how many cards are in hand (1 or 10) because Jinx's ability always enters the chain
• With legends like Teemo that don't have "at the beginning" effects, opponents would not get priority to react before hold scoring unless another "at the beginning" effect (like Temporary) goes on the chain
• Reactions can only be played when you have priority, which occurs at specific times defined by the rules
