Can you stack Orange Fiora's ability with Master Yi legend and Mask of Foresight to make her a 12 might unit when alone?

Ruling: Yes, Orange Fiora can reach 12 might when alone with Master Yi and Mask of Foresight, assuming her ability is a "while" effect. She gains +1 from Mask, +2 from Yi, and +6 from her own ability (doubling her 3 base + 3 from bonuses). However, her Chinese templating uses "when" templating, which means she would trigger once when becoming alone and keep that bonus even if the condition changes.

Nuances:

• If Fiora's ability is a "when" effect (as the Chinese templating suggests), she keeps the +6 from her trigger but would lose the +2 from Yi if another defender is added, resulting in 4 might total
• If it's a "when" effect, she could potentially trigger multiple times by charming opponents into her, gaining exponential might
• If it's a "while" effect and another unit is added to the battlefield, she would lose all conditional bonuses and return to 4 might (base 3 + 1 from Mask)
• Units are always evaluated from base stats when recalculating
