When Dragon's Rage moves a creature to a battlefield controlled by Player C, can Player C play Hidden Blade from hidden after the move but before damage, and is damage still dealt if the creature dies?

Ruling: Yes, Player C can play Hidden Blade from hidden after the move but before damage is dealt because Dragon's Rage has errata making the damage a reflexive trigger. If the unit dies from Hidden Blade, it cannot deal or take damage.

Sequence:

• Dragon's Rage moves the creature to Player C's battlefield
• Player C can play Hidden Blade from hidden (before the reflexive trigger resolves)
• If the creature survives, damage is dealt
• If the creature dies, no damage is dealt or taken

Nuances:

• The ability to respond exists specifically because Dragon's Rage has errata making the second part a reflexive trigger rather than part of the same effect
