Warding Mage
Action: Choose a unit you control. Until the end of the phase, any opponent's effect that targets chosen unit is applied to this unit instead, if able. Limit once per phase.
Helm of Fortune
Attach to target [High Elf] unit. Attached unit gets +1 hit point. Attached unit cannot be targeted by opponents’ card effects while questing.
Suppose I have a Warding Mage attached with Helm of Fortune and is currently on a quest. Someone triggered an effect that targets a unit I control and I follow up with Warding Mage's Action. When this action chain is resolved, Warding Mage's action is resolved first followed by my opponents.
So how is it resolved? is it
1) The opponent are forced to target Warding Mage but cannot due to immunity granted by Helm of Fortune and, since there's no legal target, the effect fail to resolve .
or
2) The opponent is unable (due to the "if able" in the wordings" ) to apply the effect on Warding Mage due to Helm of fortune. Action of warding mage is deemed to have no effect and the triggered, targeted effect proceeds to resolve successfully and targets the originally intended unit.
Hope to be answered!
