Mutant Traitor and Gambit's Grace

[Shadow Marvel]

When you play Mutant Traitor and use the Amplified Ammunition attack, if you trigger Gambit's Grace on the first attack of the beam, does that affect all the following attacks in the beam or just the current attack of the beam?

[Thoras]

The effect is evaluated individually, on a per attack basis. Having the required results in one of the attacks of the beam does not apply the effect to the other attacks in the beam.
