When Icathian Rain creates 6 reflexive triggers targeting two units, and the triggers resolve backwards killing one unit first, can you react to a later trigger with En Garde to buff the surviving unit (now alone) before the remaining triggers resolve?

Ruling: Yes, you can react to individual reflexive triggers from Icathian Rain. After some triggers resolve and kill one unit, you can react to a subsequent trigger with En Garde to buff the surviving unit before the remaining triggers resolve.

Sequence:

• Icathian Rain resolves and creates 6 reflexive triggers
• Opponent orders triggers (T1-T6) targeting specific units
• Triggers resolve in reverse order (T6, T5, T4, T3...)
• After T6-T3 resolve and kill the Watcher, you can react to T2
• Play En Garde on the Student (now alone, gaining +2 Might from En Garde and +1 from Student's ability)
• Remaining triggers (T2, T1) resolve against the buffed Student

Nuances:

• This same principle applies to other cards with reflexive triggers like Falling Star
• If a unit gains deflect after reflexive triggers have already chosen their targets (step 4), the caster does not need to pay deflect costs
• If a unit gains deflect before targets are chosen (step 2), the caster must pay deflect or choose different targets
• Reflexive triggers can be identified by the phrase "Do this:" or "Do one of the following:" in card text
