Does Wielder of Water retain its +2 might bonus from being alone if a showdown is contested and Tideturner is revealed?

Ruling: Wielder of Water does not retain the +2 might bonus because it uses "while" language (static ability) that continuously checks conditions. Mask of Foresight does retain its bonus because it uses "when" language (triggered ability) that checks only once and lasts "this turn."

Sequence:

• When Wielder attacks/defends alone, check if conditions are met
• Wielder's "while" ability grants +2 might only while alone
• If Tideturner contests the showdown, Wielder is no longer alone
• Wielder immediately loses the +2 might bonus
• Mask of Foresight's "when" trigger activates once and persists for the turn

Nuances:

• "While" abilities are static and continuously check conditions - they turn off immediately when conditions aren't met
• "When" abilities are triggered and only check conditions at the moment of trigger, then apply their effect for the stated duration
• Mask of Foresight specifically says "this turn" so its bonus persists even after the unit is no longer alone
