Aramasu's Mask provides the Tactician keyword, Tactical Advantage ability 'n' all, and also lets one negate an ability on a Fate card with the same Focus Value of the card discarded for Tactical Advantage in that turn.
Voice of Experience is a holding that raises the FV of a discarded or shown card by 1. Reverse Fate is a spell that raises or decreases the FV of a discarded card by 1.
Lets say for example I discard a FV 3 for a Tactical Advantage action granted by Aramasu's Mask and use Reverse Fate or Voice of Experience to raise that value by +1.
Later that turn, my opponent uses an ability on a Fate card that has 4 FV. Does the discarded card for Tactical Advantage count as a 3FV or 4FV due to Reverse Fate or Voice of Experience?

The discarded card still has a 4FV until the end of the turn, as it is still under the effect from Reverse Fate/Voice of Experience (having only gone out of play, and not also face down).
As such, when Aramasu's Mask compares the two Focus Values, it only looks at what the card has currently for a stat value, which is 4.
