When Fiora's passive triggers (doubling her might when an enemy enters the battlefield), does she immediately go from 3 to 10 might, or can the opponent respond with debuffs before the doubling resolves?

Ruling: Fiora's triggered ability goes on the chain when an enemy enters the battlefield, and opponents can react to it with reaction keyword spells/abilities before it resolves. The doubling effect checks her current might when the triggered ability resolves, not when it triggers.

Sequence:

• Enemy unit enters the battlefield
• Fiora's triggered ability goes on the chain
• Players can react with reaction keyword spells/abilities
• When Fiora's triggered ability resolves, it doubles her current might at that moment

Nuances:

• If a -4 might debuff resolves before Fiora's ability, she goes from 3 might to -1 might, then doubles to -2 might (effectively 2 might after doubling)
• If Stupefy (-2 might) resolves first, she goes from 3 to 1, then doubles to 2 might
• If Smokescreen (-4 might) resolves first, she goes from 5 to 1, then doubles to 2 might
